Topic: Universal Remote for arduino? (Read 1 time) previous topic - next topic

So I have this mini universal remote which obviously uses IR signals to cycle through well known TV models and mutes them. Sort of like the TV B-gone but better because it can also change channels and volume and so on.

I heard you can "record" the IR signal from a remote with an IR receiver connected to the arduino and then play it back so to speak with an IR transmitter. Anyone have any ideas on where I can start?

I'm kinda partial to our own implementation on the Gadget Shield:

It learns remote control sequences and stores them in EEPROM. You can then detect the sequences again, or play them back over the IR transmitter.

... not to take away business from RC but,

This will teach you how to get pulse codes from your remote.

If you click the orange "Next Step >>" button it will take you to another step that will show you how to clean up the pulse codes.

is it possible to do this WITHOUT the gadget shield?

Oh yes, absolutely. The code just assumes a few things:


  • IR logic detector on pin D2

  • IR LED emitter circuit on pin D3
