About the project

This is the result of my father wanting to control some LEDs in his model railway buildings. Over the span of a few months, I put a lot of energy and effort into creating an Arduino based Browser powered LED controller that adds interactivity and a ton of life and detail to his prints.

Story

Some time ago, my dad asked me if I knew a way to control a bunch of tiny LEDs to light up his model railway buildings. Initially, I didn’t have a solution, but I was up for the challenge. He had a straightforward wishlist: lots of LEDs, easy brightness adjustments, and some random events to add a bit of life to the mix.

The current state of our project is an open-source, free-to-use platform capable of controlling up to 256 LEDs with an Arduino MKR WiFi 1010. Everything is controllable via a user-friendly and internationalized Web App, supporting multiple languages. I've added features like LED grouping, customizable events and channel names, all backed by an external EEPROM for persistent data storage, even while reprogramming.
