Temperature controlled vents
295 lines of code, but it finally works! Little OLED screen to display temperatures and state. 2 temperature sensors to compare temps on either side. And 3 buttons, 1 to turn on the screen that times out after 15 seconds, and 2 to set heat or cool states. I know it probably isn't that impressive. But for my first coding and arduino project, I am very happy! Now to print a better vent and an enclosure for the arduino and put it to use!

Also as a question, the oled flashes random characters at the bottom every now and then and the servos twitch every now and then. When I turn off the power on the bottom the OLED keeps displaying at very low power. I am getting backfeed from someplace?
if you turn off your power supply and things stay powered, yes
