Bajdi wrote an article on using an Arduino Due with a 5inch touch screen and a wireless nRF24L01 transceiver as a remote control:
One of the things I wanted to try out was using the touch screen as a remote control. I have a lot of cheap nRF24L01 modules so I soldered one to the adaptor shield. Thankfully someone has ported the RF24 library to make it work with the Arduino Due. I made a simple sketch to remotely control 4 leds with the touch screen using the wireless nRF24L01 modules
