Introduction: OSU! KEYBOARD WITH RGB LEDs
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/
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.

I bought a strip and cut off the last 4 leds (you can cut them individually) but you can also just buy the chips themselves. The option of 30, 60, or 144 leds per meter will say how dense the leds are and the waterproof will come in silicone.https://i.ebayimg.com/images/g/WggAAOSwK6RZJBGr/s-l1600.jpg
