I want to use an infrared emitter and receiver system to comunicate 2 arduino boards.
The emitter should be able to send 5 different signals codes. And the receiver should be able to identify which code is.
Here is a tutorial which could be used as a base: http://learn.adafruit.com/ir-sensor/using-an-ir-sensor
I need somebody able to do programming with comments, send minimum schematics and also able to mantain good communication.
