The current implementation uses an Arduino Uno as its primary controller, a One-Wire based temp sensors to measure temperature, 3d-printed connector on a lead screw with a stepper motor to open/close the window.
The first three photos detail the following:
1. Picture of lead screw with 3d-printed attachment for my test window at home. First motor I used did not have enough torque to drive the window, so I'm moving to a more powerful stepper motor.
2. Picture showing LCD debug panel, showing thermometer output (I - Indoor, O - Outdoor, T - Target) along with the logic output for what it feels the window state should be.
3. A more complete view of the Arduino Uno and test breadboard.
