Motorized Blind Controller

Stepper or geared motor opening blinds from schedules and light level. Stepper or geared motor opening blinds from schedules and light level.

Components

  • MCU
  • stepper/geared motor
  • end stops
  • light sensor

Build steps

  1. Inventory the board, actuators, sensors, and power rails listed for S03.
  2. Build and inspect the low-voltage wiring against the supplied connection diagram before connecting actuators.
  3. Flash the firmware, run the startup self-check, and record the printed board and firmware version.
  4. Calibrate the sensors and limits, then run the acceptance tests at the lowest safe energy level.

Test and expected result

Calibrate end stops, obstruction handling, repeatability, and safe restart.

Safety and limits

Use a small blind mock-up and low torque.
