Raspberry Pi LESSON 69: Controlling an RGB LED with RFID Tags and Modules

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)

In today's video I will show you how to add an RFID module to your Raspberry Pi projects. I will demonstrate the concepts by controlling an RGB LED using RFID tags.

If you want to grab those cool little straight jumper wires I am using to keep my breadboard builds neat and clean you can snag a box of them here:

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.

You guys can help me out over at Patreon, and that will help me keep my gear updated, and help me keep this quality content coming:

Hi Paul,

Amazing lesson You are the BEST I was wondering in this series if you will be doing a lesson on a project utilizing what we have learned with the camera and tracking and A1 combined with the hardware we have learned to tie everything together in a project like a smart entry system or security type system. Seems this would be a good way to end the series and showcase all we have been taught in this series. Thanks much Paul

I AM LEGND! Google was my friend in solving this homework problem, including adding a tuple to the colors. It surprises me that there is so much to learn about Python. The vast libraries make Pytnon so powerful. Thanks for another great lesson, Paul.

Thanks for good explanation. I have a lot from your lessons . Than the days in my college years.

Thanks Paul Blue. That was alot of stuff in between the lines of code. I love it.

Nice video, I love the way you did the inputs. I did something similar but not as elegant. Will start the homework now, it may take me a while to get it right. Thanks for the lessons.

All my lessons with TTB have been well past when the videos were created. I've finally caught up with when these are create (well at least almost). And, I can confidently say, I have completed the homework with at least my spin on how to handle the requested program scope. I have a master admin card, that opens up a segment within the program to make changes to RFID text. I'm excited to see your approach.

U R MY FAV PAUL....MY FAV TEACHER ..I LOVE WISH I CAN BACK IN TIME MAKE YOU YOUNG AGAIN SO THAT I CAN SEE YOU U MORE ..MAKING THIS WORLD A BETTER PLACE TO LIVE ON

I have tried like mad to use the touch sensor as a touchButton to switch each tri-colour LED on, each time its touched coding in Micropython on a Pico-W. I want to turn all LEDs off on the 4th touch and start the process again on the 5th etc., (similar to another excellent lesson using a touch sensor by Paul using Python on a RPi) but I cannot for the life of me get it to work - can anyone help?
