After figuring out the IR codes for his remote, [firestorm] threw a shift register into his bread board and attached a seven-segment LED. Since [firestorm] knows the codes for the number buttons on his remote, it’s very easy to have the LED display flash a number when the corresponding button on the remote is pressed.
A single seven-segment display might not be extremely useful, but with [firestorm]‘s tutorial, it’s easy to give your Arduino some remote control capabilities with a simple IR receiver. Not bad for a few dollars in parts.
