3 tutorials selected for their relevance to our project:
1. Light sensor controlling LED (replace light sensor with temp sensor, LED with relay(heater)
2. Temp sensor (making sense of the analog signal input to the arduino)
3. Relay: good first step for our beefier 30A 120V relays
Lastly a small bonus, firefly/grasshopper(rhino) talking to Arduino!
