Blinds that can be controlled with an Arduino.
Concept derived from the Jaycar tutorial.
Measures ambient light on an LDR stuck to the window. When the light measured is greater than a set threshold, the stepper motor will pull the blinds open, and vice versa for low light levels. Also has a button to override operation.
Will replace the Arduino with an ESP32-C3 Mini Dev Board by Waveshare running HomeSpan, allowing the blinds to be operated by Apple HomeKit.
