Description: 
This is the first stage of a collaborative build of greenhouse controller. The primary purpose of this controller is to operate two motors for roll-up sides through a relay box that was built during a workshop hosted by the CAPE in Quebec. The secondary purpose is to operate a heating system with the powerswitch tail available from adafruit.
