Fixing a Broken Thermostat with a Raspberry and Cayenne

So my laundry room gets cold. I have a heater, but the thermostat broke & to always have it on or get a new one is too expensive right now.

Story

***Remember to be careful while using high voltages and check so that you don't exceed the maximum amperage or even get too close to it...!

My heater didn't work due to a broken thermostat so I decided that rather than buying a new one I'd build my own thermostat. The MCP3008 offers many more connections to be made (8 analogue inputs can be used). I used 3.3v to power the MCP3008 and TMP36 and 5v to power the relay.
