Raspberry Pi LESSON 9: Using GPIO Pins for PWM to Simulate Analog Output (Pulse Width Modulation)

Guys the pinout I show in this video has an error on Tx/Rx. You can download your own correct Pinout from my WEB site HERE:

Announcing the Most Awesome Raspberry Pi Lessons of All Times! This time we RUMBLE!

In this class series, we will be using the most excellent Sunfounder Ultimate Raspberry Pi kit, available here: (Affiliate Link)

or for our UK friends, https://amzn.to/3I5d401

In this lesson I will show how to simulate analog output voltages by using Pulse Width Modulation, or PWM. We show how brightness of the LED can be controlled through proper use of PWM signals to the GPIO pins.

If you guys are interested in the oscilloscope I am using, you can pick one up here (affiliate link):

You guys get your hardware ordered so you can follow along at home!

You will also need a Raspberry Pi. I suggest the Raspberry Pi 4. If you do not already have one, this is the most suitable gear I could find:

The Raspberry Pi's are sort of pricy right now, so you can look on ebay or elsewhere to see if there are any deals. You will need a SD card. If you do not already have one, this is a good one:

I like using a wireless keyboard and mouse to have fewer wires. You can certainly use your USB keyboard and mouse, but if you want a nice wireless one, this one works on the pi. We demonstrate this by using a button switch to control a LED.
