Hello friends, I hope you all are doing well. Welcome to the 9th tutorial of our Raspberry Pi programming course. In the last chapter, we generated a PWM signal from our Raspberry Pi to control the brightness of an LED. We also studied different functions used in Python to perform PWM. In this chapter, we'll get a bit advanced with PWM and use it to control the speed and direction of a DC motor with the help of a motor driver IC. To control the speed & direction of the DC Motor, we will: Design a Circuit Diagram. Write Python code. Components Required We will use the following components to control the DC motor speed: Raspberry Pi 4. DC Motor. Motor driver IC(L293D). Breadboard. Jumper wires. Controlling DC Motor speed with Raspberry Pi 4 In order to control the DC motor with any microcont ...
