This holiday, bring home a handmade electronic piano to amaze your family and friends. Play your
favorite tunes while showcase your programming and robotic skills.
Write one c program, using Arduino’s integrated development environment (IDE), to simulate a 12-
Key electronic piano that includes 12 capacitive touch sensor keys. Design a unique frequency for
each key. Program your Raspberry Pi Pico to play a unique frequency when each piano key is
touched or pressed. Piano keys that can play pre-programmed songs are super welcome. People
that are new to music can search “easy piano letter notes” or “popular songs in letter notes” for
frequency selection inspirations. Display a random color when playing each tune.
1. Use one (1) RGB LED to display a random color when playing each music node.
a. b. Turn off the RGB LED when no one plays the piano [10 pt]

2. Use one (1) Passive Buzzer, the buzzer with circuit underneath, to play tunes.
a. The buzzer should play multiple frequencies when multiple piano keys are touched or pressed
