Inspiration
We thought it would be a fun and interesting to learn more about hardware by making an instrument.
What it does
Using an Ultrasonic sensor, play notes along a major scale by moving your hand along the instrument. Also contains 4 preset tunes to play alongside the dynamic scale.
How we built it
We used 2 Arduino boards to output to a speaker for the main scales, and a piezo buzzer for the presets. Everything is powered by 9v batteries.
Challenges we ran into
This was the first time working with hardware for Cindy and Joseph, and was a completely new learning experience because of that. We also ran into the issue of a lack of a Digital Analog Converter on the boards we were using and needed to handle only digital signals.
Accomplishments that we're proud of
We were able to store preset songs on one chip and play notes freely alongside them.
What we learned
How to use Arduino C, breadboards, and basic circuit theory.
What's next for Techno Nimbus 2000
Getting our hands on a Digital Analog Converter, and varying the tones we can output.
