Drone Landing Pad with Arduino Timing System

This drone landing pad features an integrated ultrasonic sensor that detects a drones presence. When a drone departs the Arduino starts a timer. When you return your lap time is displayed to you. You can either try to improve your personal best or challenge a friend to do better than you (if you trust them with your drone that is). It can be printed and assembled over a weekend. ========== If you'd like to support me you can either: 'Buy me a coffee' at https://ko-fi.com/diymachines or check out our Patreon page: https://www.patreon.com/diymachines ==========
