When a pushbutton connected to digital pin 2 is pressed, the Arduino will control a transistor via pulse-width modulation (PWM), which will ramp up the motor's speed, then slow it back down. Power to the ESC is provided by a 3S LiPo battery. I will explain what is a PWM through these two examples. The low power Arduino PWM signal switches on and off the gate at the MOSFET through which the high power motor is driven. This normally takes a PWM signal from a radio control unit to control the speed of a 3 phase brushless motor connected to its output. So it don't take any computation power and delay as my method will take (using pulseIn() and converting back to PWM). I'll actually only run it up to 10A, because this is the maximum I can draw from my batteries. 5. By MertArduino Maker 101 Follow.
