Runner and Arduino enthusiast Nikodem Bartnik has created a DIY 100m sprint timer which is placed at the finish line and signals the start of timing via an audible bleep from its integrated speaker. Watch the demonstration video below to learn more about the ultrasonic race timer and its creation.
Powered by an Arduino Nano development board the sprint time is equipped with a small ePaper display together with a couple of buttons to adjust the distance from 50m to 1,000m depending on your race criteria. All code for the project has been kindly published to the GitHub website and 3D printing files for the outer case have been published to Thingiverse.
“This project will connect two things that I like, making and running! I would like to see how fast I can run 100m and that’s why I build this project, it’s simple to build, you don’t need any fancy tools and we will use popular components like Arduino, buzzer, buttons, and one that’s not so popular: E-paper display.”
