Using Wemos d1 Mini to Control a Brushless Motor @Raspberry_Pi #PiDay #RaspberryPi

via RasPi.TV

I’ve recently become interested in making “machines” of various sorts. I was sorting through some of my RC (radio control) plane “stash” the other day and came across various brushless motors and electronic speed controllers (ESC) like these. In RC, Brushless ESCs are usually connected to a radio receiver which generates servo control pulses.

So this morning I thought it would be fun to try and get a Wemos D1 mini controlling a brushless motor. I’ve done similar before. I can remember, back in the dark ages of 2013, using a Guzunty Pi to generate servo control signals to drive a brushless ESC.

I’ve also controlled servos directly with Arduino before now. This is handy because Wemos D1 mini can use the Arduino IDE. There’s also a ‘servo’ library that we ought to be able to use.
