Hardware Hacks has published a new build, a DIY Infrared remote for speaker:
The idea is simple, we capture the IR signal from a remaining speaker remote and record the commands that get transmitted. We did this by connecting up our IR Receiver to the Arduino, the receiver has 3 pins and from left to right GND, +5V, SIGNAL and using the Arduino IRRemote library. Run the Examples > IRRemote > IRrecvDumpv2 example. (see image below with the IR Receiver connected to a Arduino Uno (for prototyping, you can use the Arduino nano, but you’ll have to upload/reset the sketches when testing) If this is running correctly, point the speaker remote at the receiver and press a button – When the IRReceiver gets any data it will flash with the on board red LED, so you know it’s working. Open the Arduino serial monitor and you should see an output of the data it has received.
