Raspberry PI Recycling LED

This little project is intends to read a iCAL Stream and highlight connected LEDs in their equivalent color according to the color of recycling bins.

In Germany this is mostly something like this:

• Blue: Paper
• Yellow: Plastic Recycling
• Red: Noxious Substances
• Green/Brown : Bio-Waste / "organic"
• Gray/Pink : residual waste

Installation

1. Install NodeJS on your Raspberry PI https://thisdavej.com/beginners-guide-to-installing-node-js-on-a-raspberry-pi/#install-node
2. Clone the project on your Raspberry PI and run node.js

cd ~
git clone https://github.com/bartrail/rpi-recycling-led.git
cd rpi-recycling-led
npm install
npm start

Mapping

This project uses iCal.js to parse the iCal files. Right now fetched from https://www.mein-abfallkalender.de To map the LEDs to the appropriate Events, change the leds.summary entries to the according summary of the Event name. This wording is currently the only mapping available.

Config Adjustments

Depending on your local waste provider, you might need to adjust this.
