This is the way I did it, let me know if it works for you or if you have any improvements. The transmitter transmits the code '111.' The receiver receives the code '111' and turns on the LED. This sketch simply turns on a LED on the receiver when a button on the transmitter is pressed. I have been struggling for a few days how to get the nRF24L01 module to work with my Arduino Uno and an standalone ATMega328.
