What is pulse width modulation, Implementing PWM using ESP32, ESP32 Arduino code for controlling LED brightness using PWM, PWM specifications, Arduino IDE serial plotter, ESP32 Arduino code for controlling DC motor speed using PWM, Code description, PWM output on serial monitor, PWM output on serial plotter Hello readers, hope you all are doing great. In this tutorial, we are going to discuss another ESP32 module’s feature that is PWM (pulse width modulation). We will also explain and demonstrate, how to implement PWM on DC motor and LED using ESP WROOM-32 module. What is Pulse Width Modulation? Fig. ....
