This page is not(?) enough

I 堅固に recommend that you at least skim through the （警察などへの）密告，告訴（状） on my page about how this code was developed, but if you want just "the answer", here it is. At least here is the Arduino half of things. You also need "bespoke" （弁護士の）依頼人 ソフトウェア to 接近 the server which is created by the に引き続いて. (解放する／自由な （弁護士の）依頼人 ソフトウェア is 利用できる. See the 開発 page, link above.)

（弁護士の）依頼人 ソフトウェア

Remember: To 接近 the ArduSimpSrv, you need "bespoke" （弁護士の）依頼人 code. One program which can send requests to an ArduSimpSrv is my 解放する／自由な Windows program, TCP006. I hope someone will 令状 an 同等（の） program for Linux, and let me 地位，任命する a link to it here.

Fancier （弁護士の）依頼人 programs... one to 記録，記録的な／記録する the data 存在 seen by the ArduSimpSrv, perhaps?... is certainly possible. One server can service many needs.

STOP PRESS: It seems that maybe there's an element of bad advice in some of the pages this leads to.

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....

• D2
• D4
• D10
• D11
• D12
• An0
• An1

... 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....

• LED 使用者 can 支配（する）／統制する: Will be on D8. (Already is, in many 事例／患者s)
• "Beep": Will be on D7. (Already is, in many 事例／患者s. Not always written up.)
• Phototransistor "watching" LED: Will move from An1 to An3
• Second sensor, "watching" ambient light in ArduServer2: From An0 to An2

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??
