LED Strip Piano Guide

For my final project, I created an electronic device that can easily be temporarily installed onto a piano. This device uses a microprocessor to individually control 88 LED's. These LED's will be arranged above each key of the piano and will aid in the process of learning new songs. The intention of this device is not to replace the traditional process of learning how to play the piano, but rather to provide an alternative method of delivering musical information to the player. An example of a case in which this device would be particularly useful would be in use with a player who lacks the ability sight read quickly, but may have the ability to memorize pieces of music relatively easier.

The device is made out of an Arduino Uno, two MAX7219 LED drivers, and 88 color-changeable LEDs. The plate that the LED's are mounted onto are laser-cut fiber board colored black and slotted to fit atop all of the keys of any piano at the back of the keyboard. The plate consists of four segments that can fold up into a length of <14 inches and unfold into the length of an entire piano keyboard.
