Final Video
This is my finished project: I have finished building the table and I managed to make the patterns work remotely via an IR receiver and a universal remote. Any universal remote should work, but be wary because the receiver can be sensitive so you would want to be sure the wiring is correct; I’m going to post a schematic below, along with my documentation.
Milestone
In this video I was able to get my LED strip for my main project to work via button push. This video is considered a milestone, due to the fact that all that is needed now is to add the LED’s and mirrors to the table.
Starter Project Video
In this video, I explain how exactly my mini piano starter project works, and some of the problems I had while creating this tiny masterpiece.

Documentation
This is my code(below), as a reminder. It is meant for the Arduino Uno, but may work on the MEGA. This code also requires an IR receiver. I recommend getting multiple IR receivers, due to the fact that they are sensitive and easy to burn out (I learned from experience).
