Description

Arduino Photogate PCB

Introducing the Photogate project, an Arduino-compatible PCB designed for incredibly precise measurements in your experiments. Whether you're tracking a pendulum's period or a miniature car's speed, this U-shaped PCB delivers accurate data with ease. It's simple to integrate with your Arduino thanks to its 3-pin connector. Built with just five key components, including a 940 nm LED and phototransistor, the Photogate offers reliable performance and multiple scripts for diverse applications, from single-gate timing to multi-gate speed calculations. This is an essential tool for anyone needing dependable, accurate, and versatile optical sensing.

Please check out my GitHub repository for more information about the PCB, components, open-source scripts, pictures and more :)
