From the project

A curcuit board with RGB leds to show the live position of trains in Melbourne!

You can support my work by buying this train map through my store: https://keastudios.co.nz/store/

A physical, real-time LED map of the Melbourne train network, powered by an ESP32-S3 microcontroller. Train movements are displayed using addressable RGB LEDs, with live data fetched over Wi-Fi.

- Real-time Train Tracking: Displays the locations of trains on the Melbourne network. - Addressable LEDs: WS2812B-compatible RGB LEDs for a vibrant display. - Wi-Fi Connectivity: ESP32-S3's built-in Wi-Fi fetches live train data. - Adjustable Brightness: You can use the buttons to adjust the…
