As kids, we hated our piano lessons, yet loved playing Piano Tiles. Taking inspiration from the infamous game, we created LEKeys

LEKeys is a piano with illuminated keys that also links to a web app that guides users through the learning journey, making learning piano more affordable and fun!

For our hardware, we inserted LED lights under the keyboard keys. We used Arduino Uno to link the LED lights to nodejs.

We had to make sure that the LED lights fit under the keys while ensuring that those keys were still playable. Our team made a lot of adjustments to the keyboard, and we were able to get it to work!

We were able to pump out a clean-looking UI and highly responsive hardware.

We learned how to use Arduino and nodejs, as well as come up with ideas and risk mitigations

We are looking at importing a music sheet database to teach users to learn how to sightread. We are also thinking of implementing learning trees.
