  • Check around on ebay and see if modules for this exist (look for stuff on people doing this with arduinos).

    The other approach, of course, is to note that you already HAVE a controller and see if you can use the GPIO pins of the Espruino to drive the existing controller....

    If they're not arranged in a matrix, the switches on the existing remote control probably just ground the appropriate pin, so if the voltage on it is no higher than 5, you could just hook up the buttons to GPIO pins and drive em like that. I've done this kind of thing all the time with discrete parts, and it could save you a lot of wheel reinvention.

    I wish you luck in your plan for world domination - but not too much. I've got my own plans... I just need some fissile material, a foreboding island, an appropriate outfit (I'm thinking Gadaffi meets Lady GaGa)...
