Arduino presenter receiver
With this project, you can use Arduino as an IR receiver. Pressing a few buttons on your remote control (previously decoded) you can send commands to the computer to go back and back on your presentation. Arduino writes this commands on serial port and a running program (maded by me) gives the orders to the PC. It's in beta testing.
