    yep :)

    Controlling brushless hub throttle via Arduino, not spinning

    @jojje123 I definitely agree this might be the issue. Perhaps if I run the Arduino with the throttle power output and ground?

    Controlling brushless hub throttle via Arduino, not spinning

    Nice. Thanks. Perhaps I can reduce the cost/complexity a bit in the future by swapping the DAC for a simpler RC filter (version two). I'll post what I learn from the potentiometer test.

    Controlling brushless hub throttle via Arduino, not spinning

    Gotcha, thanks. I do already have the DAC running (via I2C) from the Arduino to the throttle, rather than just PWM. Will definitely try with a simple potentiometer for a sanity check. Sure hope I don't end up dealing with allowing current to the signal while the whole thing turns on, what a...

    Controlling brushless hub throttle via Arduino, not spinning

    @Ianhill... The third power wire (red) is connected to battery. I believe that if it wasn't connected the self-learning wouldn't be spinning the motor at all. Great to know that the brakes being disconnected is not a problem. I haven't had any trouble with the self-learning system, that's...

    Controlling brushless hub throttle via Arduino, not spinning

    Thanks for the replies. Seems reasonable that the controller could get locked up if the throttle wasn't plugged-in when started up. I did try connecting the 5v throttle output directly into the signal wire, but it wasn't connected initially (and the ground was then disconnected). With the...

    Controlling brushless hub throttle via Arduino, not spinning

    I'm trying to control a brushless hub motor via Arduino by way of the motor controller's throttle signal. Getting no spin :( To troubleshoot and calibrate I output a signal from the Arduino between 0v-5v to the throttle signal wire (green,vs red/white). I've tried voltages all over the range...
