Chameleon

This script monitors the weather at Nelen&Schuurmans (Vinkenburgstraat 2A) and controls the traffic light via a Flask API.

WARNING! Pins 8, 10, 12, 16, 18 are physically wired to switches. NEVER set those pins to 'OUT' mode as it will short circuit the pin to ground, potentially burning the GPIO or the entire RasPi!

Setup

git clone https://github.com/nens/chameleon.git
python3 lights_control.py  # make this a service permanently running
python3 weather_display.py  # run this every few minutes from a cronjob
