Raspberry Pi PWM Tutorial

Raspberry Pi is an ARM architecture processor based board designed for electronic engineers and hobbyists. The PI is one of most trusted project development platforms out there now. With higher processor speed and 1 GB RAM, the PI can be used for many high profile projects like Image processing and Internet of Things.

For doing any of high profile projects, one need to understand the basic functions of PI. We will be covering all the basic functionalities of Raspberry Pi in these tutorials. In each tutorial we will discuss one of functions of PI. By the end of tutorial series you will be able to do high profile projects by yourself. Check these for Getting Started with Raspberry Pi and Raspberry Pi Configuration.

We have discussed LED blinky and Button interface with Raspberry Pi in previous tutorials. In this Raspberry Pi PWM tutorial we will talk about getting PWM output with Raspberry Pi. PWM stands for ‘Pulse Width Modulation’. PWM is a method used for getting variable voltage out of constant power supply. We will generate PWM signal from  Raspberry PI and demonstrate the PWM by varying the Brightness of a LED, connected to Pi.

Pulse Width Modulation:

We have previously talked about PWM many times in: Pulse width Modulation with ATmega32 , PWM with Arduino Uno, PWM with 555 timer IC and PWM with Arduino Due.
