Hello friends, I hope you all are doing great. It's the 8th tutorial in our Raspberry Pi programming course. In the previous lectures, we interfaced LCD 16x2 and Keypad 4x4 with Raspberry Pi 4 . In this chapter, we are not going to interface any external module with Pi, instead, we'll create a PWM signal in the raspberry pi using Python. Let's get started: Components Required We are going to use the below components in today's PWM project: Raspberry Pi 4. LED. A resistor of 330 ohms. Breadboard. Jumper wires. Before going forward, let's first understand what is PWM: What is PWM? In PWM(Pulse Width Modulation) , we simply turn on and off our power supply at regular intervals and thus reduce the average power of the signal. We have shared a detailed tutorial on Introduction to PWM(Pulse Widt ...
