Arduino Mega 2560 & ethernet shield analogue write function from web page??

Hi all,

I have been playing with the arduino Mega 2560 with the Ethernet shield using the following set of tutorials:-

My question is can I control the analogue input from a web page?
My ultimate goal is to put this into an thermal chamber so I can have a pid loop going and be able to control a set point value from the website to change the temperature.

Any help or examples would be great.

Thanks
Steve

can I control the analogue input

What do you mean control an input.

That doesn't make any sense.

You can control outputs, but inputs just tell you what the external world is doing.

If the Arduino is running the PID system i.e it has the temperature sensor and control of the heater or cooler, then you would be able to control the temperature by controlling the Arduino remotely via a web page if you write the appropriate code (program)
