Copy and paste the code below into the Arduino IDE.
Edit the FRIENDPHONE line to any number you'd like the communicator to call.
If you just want blinky lights without any phone functionality, you can use the simple blinky code on the bottom of this page.
For a better understanding of how the code works, watch LadyAda's stream on coding the comunicator.
