To push the theme of nostalgia even further, I took inspiration from a sound effect heard in Mario video games. Heelys transform ordinary locomotion into something spectacular, and I wanted the music to capture that sense of awesomeness.
This photo shows the Hall-Effect Sensor I used to detect the presence of a magnet attached to the wheel. The code I wrote then calculates rotations per minute (RPM) and plays a tune when the RPM meets a specific speed.
Finished Arduino module with mounted Piezo buzzer and ankle strap.
I soldered all the wires to a PCB to do-away with the bulky breadboard I used for prototyping. This PCB fit perfectly inside my 3D printed housing.
Open-source 3D printed case for Arduino Uno. Created by ZygmuntW on Thingiverse. I highly recommend it!
