The Arduino is a hobbyist-friendly microprocessor. For $10 you can own a computer more 有能な than the one on-board the Apollo 宇宙船. And the ソフトウェア to program it costs nothing.
An ArduServer (my 称する，呼ぶ／期間／用語) is a web server built in an Arduino. The only （弁護士の）依頼人 ソフトウェア you 要求する is an ordinary web browser, e.g. Firefox.
Some of the デモ servers 述べるd in these pages feature an LED and a light sensor. With an ArduServer you only need a browser to turn the LED on or off, and you can "see" what the light sensor sees... from anywhere in the world! (最新の, greatest Arduserver (Esp8266 based) costs $20. See "New December 2016", below. (An "expensive" ESP8266 costs $15. I 追加するd $5 for a few discretes.)
The LEDs and light sensors are just "stand ins" for whatever effectors and sensors you want to 接近 across a LAN, or across the internet.
Some of the other Arduserver 述べるd here are おもに ーするつもりであるd 地位，任命する readings from sensors 大（公）使館員d to the Arduserver to the internet, for use from anywhere.
And then there's the ArduSimpSrv (my 称する，呼ぶ／期間／用語). It is easier to make... so the Arduino is not as "強調する／ストレスd" by the serving, and thus more other things can be done in it than if the Arduino has to be a web server. It also has an LED and light sensor, again as "stand ins". But an ArduSimpSrv needs "bespoke" （弁護士の）依頼人 ソフトウェア. I 供給する some for Windows, and would be very happy to 供給する publicity for an 同等（の） program for Linux. (See my ArduSimpSrv page for 詳細（に述べる）s.)
If parts of this page seem "時代遅れの", 井戸／弁護士席, maybe they are! But I hope that they will 安心させる you that the idea of an Arduserver has stood the 実験（する） of time!?
Today, you can build one more easily than the 早期に ones were built. For the same money, you will have more 力／強力にする. Or build one for いっそう少なく than $20. Imagine having a simple computer for $20, not so long ago. Let alone a webserver.
There were already ways to do a 極小の Arduserver やめる inexpensively in October 2017 when I am gave this page an 精密検査する.Now, in February 2019, what we had in 2017 seems 天然のまま.
Today? I would "go with" the ESP8266 "answer". That means using a wireless 関係 to your LAN, which I don't 特に like, and it would mean "任命する／導入するing" the support 構成要素 for the ESP8266 in your Arduino IDE, which you may be 気が進まない to do. Fair enough (!)... but, although I was 気が進まない to do that sort of thing long ago, I've done it 非常に／多数の times since without 悔いるs. But, even with a "poor" and "expensive" ESP8266 (from Sparkfun... which is what I would do, for 推論する／理由s explained どこかよそで), it would be $17 (加える p&p, Oct 17)
(By the way: If you have 追加するd boards, such as the 8266, to your Arduino IDE's 能力s, remember: It is best to 始める，決める the IDE for the sort of board you are going to work with "today" before connecting the Arduino to your 開発 system.)
If I didn't want to go the ESP8266/ wireless 大勝する? Though I 港／避難所't tried it, I would be very surprised if the に引き続いて wouldn't support an Arduserver 井戸／弁護士席...
Ummm... as I started 研究ing this, October 2017, I 設立する that wired 代案／選択肢s seem to be 落ちるing out of the marketplace! Bah, humbug! But you can find them... but be 用意が出来ている for having to dig around a bit. Sorry!
On 選択: the Arduino of your choice, connected to an Arduino Ethernet 保護物，者 2. Sparkfun sell them as their "DEV-11166". ($25, Feb 1019. (It was $45, Oct 17) 加える p&p). Sparkfun won't be your cheapest 選択.. but they are reliable, and give you support. (Something 名目上 類似の was on sale, eBay, for $5!) Speaking of "support", 公式文書，認める, for instance, the （警察などへの）密告，告訴（状） about the "Arduino.cc"/"Arduino.org" "war" which was 原因（となる）ing nuisance for people using this 保護物，者 in Oct 17.
The Teensy, which I HAVE used, 詳細（に述べる）s below, 許すs you a WizNet820 wired 関係 to the LAN... (&続けざまに猛撃する;36 (加える p&p, Oct 17) from HobbyElectronics, 加える a Teensy. Get the Teensy WIZ820IO Ethernet & Micro SD Card Adaptor, which was part of my "&続けざまに猛撃する;36", too.) but, like the ESP8266, would 要求する an 高めるd IDE. As I said... that enhancement is NOT a big 取引，協定... and going that 大勝する would save you money over the Ethernet 保護物，者+ Arduino 大勝する.
Enough about 金物類／武器類! Moving on...
I would like to tell you that anyone can create and 始める，決める up an Arduserver on the internet after reading just a few tutorial pages. (If you just want to use one made by me, you can "just plug it in"... 事実上!)
I'm afraid, though, that an Arduserver is a 十分な blown web server. No webserver can "just be plugged in" to a LAN, let alone to a LAN in a way that makes it (安全に) 明白な from anywhere on the internet.
If you 港／避難所't already learned "all about" the basic elements of putting anything on the internet, I 招待する you to the 一連の pages I've written for you. (The 早期に pages in that series take you through the いっそう少なく 複雑にするd 問題／発行するs of getting a server 明白な inside your LAN... a necessary first step.)
If you 港／避難所't worked much with IP 演説（する）／住所s, DDNS, ports, servers: ざっと目を通す what is below, and say to yourself "That sounds fun"... and then go off to the pages about putting things on the internet. You will thank me, in the long run! Or waste a lot of time learning the ropes the hard way, as I did... 集会 "捨てるs" of knowledge in the wrong order!
My さまざまな Arduservers WORK!
To the left: A screenshot of what someone out on the 逮捕する sees when he 接近s the server. (The globe is a 訪問者 監視する 力／強力にするd by a plug-in on the code 生成するd by the Arduino/ Teensy.)
At the 底（に届く） of the page there is a big "stop 圧力（をかける）" message with 警告s that some stuff may be wrong.
That "wrong stuff" is mostly some rough 辛勝する／優位s in my advice on what pins to use, what pins to 避ける. It needs work. But the さまざまな Arduservers 述べるd here DO WORK. And have been working, on and off, for years in some 事例／患者s.
Of course, 網状組織s, modems, routers go 負かす／撃墜する from time to time. Email me if an Arduserver that "ought" to work seems 負かす／撃墜する.
A new 見解／翻訳／版 of FarWatchWatcher, to go with the ソフトウェア I created for my 8266 Arduserver... or with the IOT 装置 of your choice, if you can 挿入する a line into the 生産（高） the IOT 装置 produces. (That ソフトウェア would "fit" in other IP/TCP 有能な Arduinos, too.)
The 8266 Arduserver isn't new, and most of the code for it would run in any IP/TCP 有能な Arduino. But I hadn't given you a like to its page before now.
All of the さまざまな "FarWatchWatcher" 使用／適用s let you gather data from IOT 装置s and use the data. "Gather" across your LAN (平易な) or the internet, depending on how 広範囲にわたって 明白な your IOT 装置 is. Most will build graphs of the data in real time. Most will save the data gathered in a machine readable とじ込み／提出する.
An Arduserver serves up pages to the internet. The pages have on them readings from sensors 大（公）使館員d to the Arduserver. Arduservers are 子孫s of my FarWatch 製品s. In January 2017 I 解放（する）d a new "Far Watch 選挙立会人".... it is a program that runs in a Windows PC and "watches" an Arduserver or FarWatch 取り付け・設備, across the internet, 製図／抽選 graphs of the numbers fetched, and 記録，記録的な／記録するing the numbers in a data とじ込み／提出する.
Too 冷静な／正味の! There is now a little micro-加工業者-with-WiFi which can "do" all of the basic Arduserver stuff... and only cost you $16!! (You'll have to 追加する a few resistors and a light sensor. Big 取引，協定. All the Arduservers need them. You DON'T have to 供給（する） an internet controllable LED. There's one on the board, and a デモ program for creating a web-server that only needs minor tweaking to make an Arduserver out of the 装置.)
It has been around for a while, even the 明確な／細部 "完全にする 製品" which has me all excited, built around the Wonder 半導体素子 that makes it all possible, the ESP8266.
Some time ago, Sparkfun created what they call the ESP8266 Thing. (It comes in two 見解／翻訳／版s. Both $16. I 選ぶd for the "Dev Board" 見解／翻訳／版.)
It isn't "an Arduino", but, with one of the ますます ありふれた "追加する on" 一括s, you can use the basic Arduino IDE to program the Thing. I've used such 追加する-on 一括s without grief.
And, oh by the way, it runs at EIGHTY megahertz! (An Arduino プロの／賛成の 小型の runs at 8 or 16 megahertz, depending on the voltage variant you are using.
Use the link at the 最高の，を越す of this section for all the ソフトウェア, etc, to create an Arduserver in an ESP8266, 含むing an explanation of how to use an ESP8266 for an Arduserver. That Arduserver uses わずかに different 命令（する）s to turn the LED on or off, and there's a separate 命令（する） to read the value on the analog input, but the basic "ArduServer" features are there. The code also 含むs ソフトウェア to read a 1-Wire 気温 sensor. (I've 実験（する）d it with a DS18B20. It "should" also work with DS18S20 or DS1822.)
Oh.. and it does 天然のまま "pulse counting"... 適する for a 勝利，勝つd 速度(を上げる） sensor.
The web-page 生成するd by that Arduserver is "machine friendly", so if you have the Arduserver running in one place, you can have a "check the Arduserver" program running どこかよそで which will draw a graph of the 気温s seen, and the values in the pulse 反対する. The same "Arduserver 選挙立会人" program can sound an alarm if, say, the 気温 the Arduserver is watching 落ちるs below a 確かな level.
Besides the Arduserver ソフトウェア, which you pretty 井戸／弁護士席 have to 人物／姿／数字 out for yourself... I 供給する the code, but not a lot in the way of tutorial... I've written more for you on the Sparkfun Thing on a 献身的な page.
N.B.: The analog input to the Thing should not be 支配するd to more than 1.0 volts. Not a 取引，協定 breaker, but you'll have to 始める，決める the light sensor up accordingly.
I've 追加するd an ArduWatcher program to the system. It 収穫s data from Arduservers, across '逮捕する of LAN, saves it in a CSV とじ込み／提出する for 平易な その上の 過程ing.
I first started playing with the wonderful Teensy in 早期に November 2014. Within a few days, I had Arduserver 3 up and running... the best Arduserver to date. Some problems I'd run into 以前 with pages 存在 厳しく 限られた／立憲的な as to size... and the 開発 環境 答える／応じるing very 不正に if a page was a tiny bit to big... seem to be GONE, in the Teensy world. Of course, they may also, by now (Nov '14) be gone in the general Arduino world... it is a while since I was last working on Arduservers. But no time just now to 調査／捜査する that!
Want to see one in 活動／戦闘? The に引き続いて page 述べるs 明確な／細部 servers which are usually online for you, and has links to them. Directory of online ArduServers.
I have written tutorial pages about IP 演説（する）／住所s, the DNS, dynamic 演説（する）／住所s, etc., several times! The 始める，決める of pages I について言及するd earlier is my "最新の and greatest" at October 2017. However, an earlier guide to TCP/IP stuff may be more to your taste. (If you happen to read both, I'd be 利益／興味d in your 見解（をとる）s.) Both try to help you see how you can 始める，決める a server up on a LAN or even to serve the internet. There are also many 詳細（に述べる）s in さまざまな pages about my different ArduServers and ArduSimpSrv... and in my FarWatch pages. The sorts of things you will find out about there....
1) The 初めの "ArduServer" is 安価な! (But if you don't have a ENC28J60 interface already, skip over this to the next item, unless you are working on a very tight 予算, or curious!)
The 初めの ArduServers was built for $40 with a Microchip ENC28J60 半導体素子 on a NuElectronics 保護物，者 and a ModernDevice RBBB with just a little Atmega168, which has only 16k of 貯蔵! (NuElectronics is no longer with us, and for a 極小の (but やめる 適する!) Arduserver today, you would spend いっそう少なく than $40.
(This page was started in 2011. Please see my "March 2015 ENC28J60 update" page before buying or using one of them! (That page will open in a new tab. Just の近くに it to come 支援する here.))
The RBBBs will take more modern 半導体素子s, and are, October 2011, 供給（する）d with Atmega 328s, your choice of 5v or 3v3 見解／翻訳／版s. 道具s (平易な): $13. 道具 with USB one-cable/ many Arduinos "BUB": $25.) (You will need a BUB or 同等（の） with RBBBs and 類似の.)
Although a Wiznet W5100 interface is probably 価値（がある） the わずかに greater expense, the SheepdogGuides tutorial for the 初めの ArduServer has （警察などへの）密告，告訴（状） on general 問題／発行するs which you may find 解決するs one or more mysteries for you.
The 完全にする code for the ArduServer, first 見解／翻訳／版, is on a page of it's own, if you want to "skip to the answer". The tutorial explaining the design and 開発 of the ArduServer will help you understand what is there.
2) ArduServer2... I've written 公式文書，認めるs, with Arduino code, on my second ArduServer, "ArduServer2", but they (at the moment) are intertwined with general ArduServer 公式文書，認めるs... sorry. I am working on untangling them.
The Arduserver2 is Wiznet W5100 based. (This section was written before I'd "met" the Teensy and Wiz820io. See Arduserver3 (below) for what, Dec 2014, I think is even better than an Uno, etc, and a W5100)
One of the "Wiznet" boards is probably "the way to go" for a beginner... even though it is a little more expensive. I'd 避ける the ENC28J60 boards... there's a 推論する／理由 they're cheap!
Taking your first steps into this 領土? One answer would have been an Uno + 保護物，者, or the Sparkfun Ethernet プロの／賛成の ($55, Oct 11 (no SD card 運送／保菌者)) which gives you the two of them on one PCB, if you are ready to commit "an Arduino" which always has an ethernet 保護物，者 "大（公）使館員d". (But hat 製品 has been retired. Sigh.) There's also the "公式の／役人" "Arduino Ethernet", with or without PoE module, as 控訴s your needs. (You can retrofit one). (About $60 , Oct 11, for one without PoE.) www.coolcomponents.co.uk used to 申し込む／申し出 something nice. And 公式文書，認めるs. Gone, Oct 17. Then there's the Freetronics EtherTen (was$70... Oct 2011... But "now", October 17: $45!! With micro SD card 運送／保菌者!)... and it even has a PoE ("力／強力にする over Ethernet") 選択.)
The 完全にする code for the ArduServer2 is on a page of it's own, if you want to "skip to the answer". The tutorial explaining the design and 開発 of the ArduServer will help you understand what is there.
Arduserver2 was retired, still working, November 11th, 2014. It's place on the web was given to...
3) Arduserver3... Built in a Teensy, with a Wiz820io ethernet module.
The 完全にする code for the ArduServer3 is on a page of it's own, if you want to "skip to the answer". The tutorial explaining the design and 開発 of the ArduServer will help you understand what is there. Although I was using a Teensy 3.1, the code should need little, if any, tweaking to work in a 正規の／正選手 Arduino.
The code the link above takes you to does work, and has been "tidied up" for reading. It is 現在のd in a web page. Alternatively, the Teensy code I am 現実に using in Arduserver3 as of 早期に December 2013 is 利用できる in the zip とじ込み／提出する the link will take you to. It hasn't been "prettied up" for reading. But a few 半端物s and ends of the 機能（する）／行事ing of Arduserver3 have been tidied.
I enjoy the challenge of Making It Work. 令状ing it all up is いっそう少なく enthralling, and いつかs I wonder if anyone even reads these things. I give away the sourcecode... you don't even have to "登録（する）", etc. So it would be NICE if SOMEONE, anyone, would "投票（する）" for the YouTube ビデオ, "Like" the Arduserver Facebook page, について言及する Arduserver in a 会議, etc, etc???
Special 公式文書，認める 適用するing to Teensies: This is a 公正に／かなり esoteric 問題／発行する, so don't let it worry you if you don't want to fuss with it. Every Teensy 3 has a unique Ethernet マスコミ 接近 (MAC) 演説（する）／住所 burnt into it. The number will be different on every Teensy 3. It isn't overwritten by the bootloader flashing 過程. If you want to 接近 this, to 確実にする that you don't get MAC 演説（する）／住所 衝突s on your LAN (ありそうもない, unless you have more than one "home made" 装置 on the LAN, but possible, if you are using the "始める，決める in code" method used in my ArduServer3 ソフトウェア), see the Teensy MAC 演説（する）／住所 thread at the PJRC 会議. Be sure to read past the first 地位，任命する, to see the suggestions for 改良s which were given.
Arduserver 3 support 回路・連盟s:
(A small point: I believe that the Wiz820io probably needs about 175mA of 3v3 利用できる to it. So don't try to 力／強力にする it from the 3v3 pin on a Teensy.. at best, that should not be asked to 供給（する） more than 100mA. The PJRC.com 保護物，者 ($6) 含むs a voltage regulator to 力／強力にする the Wiz820io, from the general 5v 供給（する）d to the Teensy.
4) ArduSimpSrv... HTML-いっそう少なく TCP/IP （弁護士の）依頼人 / server work: Going a step その上の, I have produced Arduino and Windows code for what I call ArduSimpSrv. This is still an Arduino server, but it is not a web server, it is a more Simple S(e)rver. Good because it 需要・要求するs いっそう少なく of the Arduino, leaving space for more code to do things besides communicating with （弁護士の）依頼人s. Bad because you will have to adapt the （弁護士の）依頼人 ソフトウェア I 供給する, to 会合，会う your wants regarding 接近 to your ArduSimpSrv.
The 完全にする code for the ArduSimpServer is on a page of it's own, if you want to "skip to the answer". The tutorial explaining the design and 開発 of the ArduSimpSrv will help you understand what is there.
A wise person once said "If you want to be 安全な, do nothing."
I want to do something, so I've given up 存在 完全に 安全な... but I try to 避ける 存在 無謀な. (Another 説 for you, from the world of 航空: "There are old 操縦するs, and there are bold 操縦するs. But there are no old bold 操縦するs."
Putting a server on your LAN creates new ways for things to go wrong. Putting a server on the internet will, if you aren't careful, give the Bad Guys a way into parts of your system which you don't want them in.
I've written more on the safety 面s of putting a server on your system. I'm afraid I don't have "the answer"... but maybe I can make you aware of some of the questions you need to ask?
With the things you can learn in these tutorials, you are 90% of the way to a system with a web （機の）カム or IP （機の）カム 機動力のある on a pan and 攻撃する bracket which can be controlled from across the internet! (Arranging to 見解（をとる）, across the 逮捕する, what the camera sees is another 事柄... which you will have half solved along the way to getting your ArduServer or ArduSimpSrv working.)
That's just one of many, many 可能性s. How about a system which 許すs you to 支配（する）／統制する the setting of your home's thermostat? I'd 連合させる that with your alarm system. When you go out, and 始める，決める the alarm on your home, it would automatically 始める，決める the thermostat 支援する to a lower setting. On days when you return home at a 直す／買収する，八百長をするd time, the Arduino 扱うing the alarm would turn the heat 支援する up ahead of your arrival, just in time for the house to be warm when you arrive. And on other days, a quick visit to a webpage served by the ArduServer in your home could turn the thermostat up in 前進する of your earlier- than- usual return.
So many ideas... so little time! With the basic 道具s explained in these tutorials, a whole world of new 事業／計画（する）s become (almost) trivial.
In March 2013, I had a new burst of energy, and wrote some "new" pages, pulling together many things I've learned about （弁護士の）依頼人/ server 計算するing. (The Arduserver is an example of （弁護士の）依頼人/ server 計算するing, as are the IP （機の）カムs I was speaking about a moment ago.) I hope you will find useful my March 2013 pages about （弁護士の）依頼人/ server 計算するing. I hope the enthusiastic hobbyist/ student will find them accessible that they (hobbyist/ 熱中している人) will not have (undue!) trouble 遂行するing the things 述べるd in the pages.
It may be a bad idea to use any of the に引き続いて at the same time as a W5100 based 保護物，者....
... and D13, but this last one only if you "care" that on the 保護物，者 it goes to an LED, and from there through a resistor to ground. (This 単に 平行のs the same thing on many Arduino and clone boards... BUT, to digress from the digression, BE AWARE that the ソフトウェア behind "体制／機構()" and "宙返り飛行()" pulse D13 high 簡潔に before 遂行する／発効させるing whatever you 明示するd in "体制／機構()".)
Of course, I unwittingly used some of those lines in my designs. The designs SEEM to work, but it would be a good idea to take what I've put on those lines and move them どこかよそで. I will 徐々に be 改訂するing my designs as follows....
In every 事例／患者, to 修正する the ソフトウェア is 平易な... but you will need to look carefully to see whether what is 現在／一般に online has been 修正するd or not.
To change the line used for, say, the phototransistor watching the LED in, say, ArduServer2, the line....
（弁護士の）依頼人.print("<br>Analog input 0 reads: <b>");
（弁護士の）依頼人.print(analogRead(0));
... must be changed to...
（弁護士の）依頼人.print("<br>Analog input 1 reads: <b>");
（弁護士の）依頼人.print(analogRead(1));
... and you are done! (You'll have to move one wire on your breadboard, too, if you had it wired for the 初めの design.)
(Digression: Is nothing every 平易な? In 99.0% of my code, such a change would 単に have been a 事柄 of changing something like the "const byte bLEDpin=8;" at the start of the program. But in this 事例／患者, to 避ける fighting with... not hard... getting the 誘発する to identify the channel, I took a shortcut and 明示するd the channel explicitly instead of a 全世界の variable. Sigh.)
Sorry! I could have done without this, too! When will the 公式の／役人 Arduino 場所／位置 have proper documentation of the ethernet 保護物，者 and library??
Once you have an Arduserver working, consider the に引き続いて...
A program like my FarWatchWatcher could be written with very litter more trouble than 令状ing the basic FarWatchWatch entails. Call it "ArduserverWatcher" if you do 令状 it, please. (And tell me where it is.)
I know that FarWatchWatcher is very "do-able". And I know that it would be trivial to 延長する it, very わずかに, to make it 記録，記録的な／記録する the data 収穫d in a machine readable とじ込み／提出する. (Just have it 令状 a .csv とじ込み／提出する, and you can 輸入する it into a database at your leisure.)
A "better", but いっそう少なく trivial answer would be to have ArduserverWatcher 令状 the data it collects 直接／まっすぐに to a database. The only 妨害 to that 解答 is that you not only need an Arduserver and an ArduserverWatcher, but also something like an always on MySQL server, and the ability to put database 接近 into your ArduserverWatcher code. (The latter should be possible with Lazarus/ Piette's ICS/ MySQL... all 解放する／自由な).
The last two 必要物／必要条件s are not an insuperable 障壁s... just "little extras" which may leave you content at the "Arduserver 令状s to .csv とじ込み／提出する for 結局の 統合，差別撤廃 into database" 解答. But the "bigger" 解答 really is "better". I just wish I had time to 器具／実施する it myself! So many 事業／計画（する）s, so little time. Sigh.
This page used to... and the "main", "現在の" copy of it still does!... have a RevolverMap here. They are very 冷静な／正味の! If you have your own web-pages, get one! I've had several for years with no 悔いるs.
What I had to say about RevolverMaps when I first 任命する／導入するd it. (I feel the same way today!)....
Sorry, folks... couldn't resist! I hope you find this widget as 冷静な／正味の as I do. Play with it... See what happens when you drag on it with your mouse. You can easily 追加する one to your 場所／位置, 解放する／自由な. Just visit www.revolvermaps.com. You have many 選択s on the widget design page, which is a paragon of 使用者-friendliness. At one point, you can 跡をつける individual pages or page 始める，決めるs... I'm not sure that "page 始める，決めるs" is still supported.
But! 広大な／多数の／重要な news! In "the very old days" (before 10/17) Revolvermaps were Flash based. They have used Javascript since before that. You can update old scripts to new ones without losing old 訪問者 data. The code is not HTML 5 compliant, but 実証するs under 4.01 過度期の.
A RevolverMap also gives you 接近 to 名簿（に載せる）／表（にあげる）s of what countries you were visited from. More at my page for web page authors. On modest 装置s... Kindles and iPads, for instance... you won't see the 回転するing globe that others see, but you still see something. (Don't you?)
If you are 用意が出来ている to give up the space 要求するd for the RevolverMap in the HTML for the page served by your Arduino, you can even have one on your Arduino-served-page. This is 論証するd in the ArduServer2. The 初めの ArduServer, running as it does in very 限られた／立憲的な 金物類／武器類, does not have the space to run a RevolverMap. <;-;>
(There are search 道具s, etc., in the page footer, after the 捨てるs.)
A 装置 for serving a webpage to LAN or internet, using just....
You don't need to leave your "big computer" connected to the Arduino, or switched on, once you've used it to program the Arduino... if your router can 扱う DynDNS updating.. as many can. (If your's can't, your PC can do the 職業, but then it will need to be left on.)
For one of the ArduServers 現在のd here, you don't need more than...
All of my Arduservers 監視する some inputs of the Arduino, and 現在の （警察などへの）密告，告訴（状） about what has been seen on the webpage served. What input you 監視する, what 報告（する）／憶測s you 生成する are easily 修正するd.
All of my Arduservers 許す 使用者s of the page served to "問題／発行する 命令（する）s" (by clicking buttons on the webpage returned by the webserver). The Arduino, in 返答 to the 命令（する）, changes the 明言する／公表する of one of its 生産（高）s. This 行為 can be 修正するd easily, too.
Not because it is useful, but because it is 削減（する）, and illustrates everything, in my ArduServer デモs, the 生産（高） turns an LED on or off, and the sensor is a light sensor the LED is up against. So on the web page you can "see" the LED turned on or off.
Solved for you: the problems of 打ち勝つing the fact that you probably don't have a static IP 演説（する）／住所 for your internet 関係.
