2 Arduinos, both set up to turn on a LED when they see another LED flash thru a LED connected on the analog in pins. Kind of demonstrates well how LED's can be used in reverse as light to voltage converters.

Might try transferring some simple data via it or something when I'm bored next.

  • How to do you have the LEDs hooked up to the ADC inputs? Do you connect the other end to ground or +V through a resistor or something?

  • Cool experiment. Thanks for sharing!
