# UniBikes

Inspired by [traintrackr](https://www.traintrackr.io/) I wanted to create something similar for visualizing bikesharing bikes as my first ever PCB design.

![An image of the finished PCB](https://raw.githubusercontent.com/strifel/UniBikes/refs/heads/main/unibikes.jpg)

Unibikes shows the 10 bike sharing locations at TU Dortmund University in germany with an RGB LED each.

Each LED can therefore represent if there are none, some or a few bikes at that station.

## Data

The micropython code directly receives the rgb values for each LED from a backend.
