  • This is probably the strangest "project" I ever made...

    Since none of the five 360° servos in a set bought on eBay worked, and the dealer's "assistance" was limited to repeatedly telling me the required pulse widths, I built a setup using an "Original Espruino" as servo controller and recorded a "proof video" to show:

    • voltage, current and pulse widths are correct (this shows a competitor's product)
    • in fact, not a single one of the servos supplied worked!

    The video is available on Vimeo

    Thanks to Espruino, experimenting with the servos and testing them was just trivial - and all the rest took less than an hour to build, record and upload!

    FYI: the code I had to write for the proof video was just

    analogWrite(C7, 0.10, {freq:100});
