Hey guys, I have some code, on the arduino, that turns an LED on pin 13 on or off, depending whether it gets a 1 or a 0 incoming on the serial port (COM14). I want to be able to turn it on or off from my tablet/smartphone etc, so I have an IIS webserver. My question is, how can I have a button on a webpage that can send a 1 or a 0 to COM14 on the webserver to turn it on?
