Build a Smart Helmet Backlight with Brake Detection & Custom Animations!

If you’ve ever wanted to upgrade your cycling gear with a smart backlight that’s not just functional but also customizable, this project is for you! I recently created a helmet backlight that detects braking, displays animated light patterns, and allows for full color customization — and I recorded the entire process in a video!

In the video, I break down everything: • How I integrated brake detection for improved safety. • The hardware and coding needed to enable custom light animations. • The simple tools I used to make the lights configurable via color settings. • A live demo showing how it works in real life!

This project is perfect for DIY enthusiasts, tech lovers, or anyone who loves combining functionality with style. Whether you want better visibility on your rides or just love creating smart gadgets, I guarantee you’ll find inspiration in this build.
