Totem

Let's show messages in the Hackerspace!

Installation

dispatcher.py

• Install RPIO: https://pythonhosted.org/RPIO/#installation (the GitHub method seems to work better. You may need python-setuptools)
• Install RPLCD: https://github.com/dbrgn/RPLCD#installing
• Install RPi.GPIO: pip install RPi.GPIO

Web Manager

See Web Manager README

How to Run

First, start the dispatcher with: python /root/totem/dispatcher.py (we don't live in the past so it's python 3).
And then, start the Web Manager with: cd web-manager and meteor.

Note: you may need to change the IP address of the dispatcher in Web Manager global file: web-manager/00_globals.js
