ESP32 Code for Controlling DC motor speed using PWM. Fig. 10. In this example, we are going to implement PWM using ESP WROOM-32 to control the speed of a DC motor. The speed of the DC motor depends upon the input power supply. So, by varying the power input we can also vary (increase or decrease) the speed of DC motor. The ESP32's analog input pin converts the voltage (between 0v and 3.3V) into integer values (between 0 and 4095), called ADC value or analog value. We can connect the potentiometer's output pin to an ESP32's analog input pin, and then read the analog value from the pin. The analog value from input pin can be rescaled into another value.
