Any exercise is a positive thing, but if you’re looking to improve over time, you’ve got to measure your performance. [Nikodem Bartnik] is a runner and is looking to improve his sprinting abilities. Naturally, an Arduino is the perfect companion to help in this quest (YouTube link, embedded below).
The Arduino is built into a 3D printed enclosure, with several buttons for input. Rather unconventionally, a small e-paper display was chosen for the interface. This has the benefits of being easily readable outdoors during the day, as well as using very little power.
The device is simple to use, and makes training alone a breeze. The distance to be run can be selected, and the unit emits a series of beeps to indicate to the runner when to begin. The timer is placed at the finish line, and detects the runner passing by with an ultrasonic sensor.
It’s a useful build for sprint timing, and could be made even more versatile with a remote start function. If you need to time Hot Wheels instead of sprinters, don’t worry – there’s a build for you too. Video after the break.

Nice job… very well done. And well-made video as well!
Love the choice of the E-ink display as well. Perfect for this outdoor application.
Nice build your training plan is horrible though.
Cool build, I liked the e paper display.
Anyone looking to build one should also check out the one I made a few years ago if looking for extra ideas.
Do you have any ideas on how to build a wireless swimming timing system? Or where do I find information to do it?
