I want to share with you my solution for remote controlled window blinds.
What it does:
- control up to 4 blinds
- open/close blinds separately
- open/close all blinds at once
- open blinds separately for one second (I use it to have strips on my day and night blinds)
- one button to stop all blinds
What do you need:
- arduino board (I used arduino nano)
- end switches (2 switches for every blind)
- 10k resistors (1 resistor for every switch)
- IR receiver
- LM 7806 voltage regulator
Of course you need servos with ability for continuous rotate.
