  • @DrAzzy that's what I'd suggested in the write-up I believe. With a decent length of wire going to the LEDs I felt it needed a decently low resistance to get a nice clean waveform.

    @Mrbbp so you're using Espruino Pico?

    As you say you'll struggle to get more than 400mA out of USB on the Pico, as there is a fuse in there to stop accidental shorts causing problems.

    I'd use an external 5v supply. Does this diagram help?
