Blink test

For a simple test you can use a couple of Arduino boards, connect together their ground and pin 12.

 Arduino UNO        Arduino UNO
  _________   wire   _________
 | ||   |_||___     |         |
 ||       ||   |    ||       ||

 ||       ||   |____||       ||
 |_________|        |_|_|__||_|
                      

Flash on both arduinos the programs present in the BlinkTest directory. You should see the receiver device blinking every second.
