  • This would work with any Espruino - just need to change the pins.

  • Nice - thanks! Is this an old Apple remote? I assumed the Apple TV remotes were radio rather than infra-red.

  • It is the white remote that came with a gen one Apple TV. I'll take a picture and upload tomorrow.

  • Nice! Which IR sensor are you using?

  • jaycar.co.nz/Active-Component­s/Optoelectronics/Optocouplers/IR-LED-Re­ceiver/p/ZD1953

    IR LED Receiver

    CAT.NO: ZD1953
    TSOP4136 IR ReceiverConsists of PIN diode, pre-amplifier, AGC, pass filter, and demodulator. The main benefits are high speed data rates, short burst ...

    It's the 36 rather than 38, but that was 3x the price and it seems to work fine!
