The first step is installing the requisite packages. Because we are going to make use of the Fitbit tracker, we need to install the fitbit python client:
sudo pip3 install fitbit cherrypy schedule
If you are going to make use of the Pimoroni Blinkt LED strip, you should install the following package:
sudo apt-get install python3-blinkt
If you are going to be making use of the rainbow HAT, the following package needs to be installed:
curl -sS https://get.pimoroni.com/rainbowhat | bash
