DIY Homebrew Kegerator Thermostat

Here’s a picture of a project I recently completed: a thermostat for controlling the temperature in a homebrew kegerator. I am using a small chest freezer which can hold two cornelius kegs and associated CO2 tank. I could have spent the $ to just buy a nice digital one, but I had some parts on hand and picked up a few parts from Adafruit and pieced it all together for much less.

Uses an Adafruit 0.56″ 4-Digit 7-Segment Display w/I2C Backpack and the DS18B20 Digital temperature sensor.
