Hello I made an Instructables a while ago and I forgot to make an updated for the WS2812B RGB. Sorry. This project will build on top of https://www.instructables.com/id/Osu-Keyboard-with-Arduino-Uno/
Teachers! Did you use this instructable in your classroom?
Add a Teacher Note to share how you incorporated it into your lesson.
Step 1: Adding the WS2812B RGB
I bought a strip of WS2812B on Ebay and cut off the last four leds. I solder the 5v together, the Ground together and daisy chained from pin 11 to Din down all leds. I hot glued the first two leds to the bottom and two underneath the gateron switches. I also added a small push button to change modes and connected it to pin 2 and 3.
Step 2: Feets
In the previous project I used rubber feets and they slid around as I was playing. I removed the feet and replaced them with double sided tape. I used this Scotch Restickables. They work much better and I just need to wipe them with a little bit of water to clean dust. However because the tape makes the box not as tall, the RGB leds on the bottom are no longer visible.
Step 3: Code
This is the code that I wrote that has the modes: Cycle, Reactive, Rainbow, BPM, and off. For Reactive I can change the color by holding the mode button and then I can chose the buttons color by holding gateron buttons until keyboard cycles to color of your chose.
After a while I noticed that I only use the Cycle mode so I made a simpler code with only that mode and also didn't use the bottom leds.
