A wireless timing system for Track and Field #Arduino

Here is an inexpensive track and field timing system using Arduino:

During my Track and Field training sessions, my coach often expressed his desire to have a more precise way of measuring an athlete’s performance. I realized that an affordable, wireless and precise laser gate timing system made of easy to find components should be possible.

Accounting for the different prices across the world, absolutely all of the components and parts needed for the complete system should cost around 100USD. This is a major price difference with other systems, considering that it has a very decent precision and has a wireless range that exceeds almost any Track and Field oval in the world.

Details on the project, PCB board files and Arduino code are all provided.
