Sonar Sensing Race Gate

Summary

I made this sonar-sensing race gate as a fun way to improve my FPV skills and have fun with friends and spectators.

Work Product

Here are the designs and code I made while working through the project. The source sketch for the Arduino code came from the "Cylon" demo that comes with the FastLED library.

1. Race gate design on Thingiverse (Fusion 360 design)
2. Sonar sensor case design on Thingiverse (Fusion 360 design)
3. Arduino sketch (Dependencies: TimedAction, FastLED)
