• I'm not quite sure what you're planning with the scale, but it looks to me like you only connected one wire... You'd need to connect ground up between Espruino and the scale as well.

    Also, maybe the signal out of it is actually PWM? I have no idea what you've connected to, but maybe you should try and use an oscilloscope to see what the value out of it is actually doing?

  • @Gordon the Espruino is connected to the ground of the scale as well.
    The way we are using the scale is by hopefully waiting for a signal from one of the LCD "plates" so I have no idea if the LCD scale is in PWM. I doubt it though.
