Track Pacer
Interactive LED pacing system for a 200m track
A full hardware-software system that helps runners train with precise pacing. Runners set custom presets for speed, color, and distance in a React Native app; WS2812B LED strips light up in sync with a moving animation in the app. ESP32 microcontrollers in junction boxes around the track synchronize over ESP-NOW, while the app controls the system in real time over Bluetooth LE.
