data transmission with a led as sender and receiver

Data transmission demo between two Arduino Uno.

Connect a ultra bright red led to the ADC0 pin of an Arduino Uno in series with a 160Ohm resistor.
Both Arduinos will blink randomly. If the see each other, they synchronize and start data transmission with approximately 1500 BAUD.
