Inspiration
We've been wanting to make an Arduino project and figured this was the perfect opportunity to try it out! As a baseline we used the example keyboard on the Arduino Education page (https://www.arduino.cc/education/arduino-instruments).
What it does
Allows users to play 4 notes by pressing buttons on the board.
How we built it
With a resistor ladder and piezoelectric buzzer.
Challenges we ran into
For some reason our resistors were having a hard time staying in the breadboard, so we had to be really careful not to displace anything. We also had to experiment with different resistors to get a current that would produce the correct tones when paired with our code. Loose components sometimes create a gargle in the sound.
Accomplishments that we're proud of
Learning about circuit components, resolving sound errors, and having a working project in the end!
What's next for fingy noise
We wanted to make a 'Simon Says' type game where players must press the buttons in a certain order and be rewarded with a MIDI song upon success, but unfortunately we didn't get to it. In the future, we'd like to add this functionality.
