bimlights

A physical map of 50 LEDs to represent the tram stations in Linz, Upper Austria, which display the location of trams in real time.

architecture

server

A simple webserver written in python based on flask. It simply queries linz.faehrt.at for the location of all trams and calculates their closest station using the mapping file.

client

The client uses only a ESP8266 module to connect wirelessly to the server, invoke an update of the data every 10s and display the updated data.
