Then we will calibrate and arm the ESC and start giving some speed to the motor. To use PWM in Raspberry Pi, we need to initialize PIGPIO library in daemon(which means running the process in background) which sends DMA timed pulses from Python. We can say that it is like a servo which also takes input in pulsing signals so we will use Pi's Pulse Width Modulation (PWM) system. So, It runs a brushless-motor by sending a sequence of output signals to it. It takes a signal from a micro-controller and convert it into three-phase output of limited voltage. Also, make sure you are going through precautions at every step, its kinda important if you don't wanna screw up your life.Īn Electronic Speed Controller or simply called ESC is an electronic circuit which is basically used to control a brushless-motor. I am making this instructable because I didn't find any tutorial for this topic, maybe because the ones who already knew how to do it were too lazy and selfish to help others. I recommend you to READ THE WHOLE INSTRUCTABLE BEFORE MAKING IT even though I'm typing load of crap here. Hey there!!! In this instructable I will show you how to program an ESC and drive a brushless-motor in a desired speed using Raspberry Pi 3.
