Smart Curtains

Overview

Voice module: HLKV-20
raindrop module: ...
Light module: GL5528 photoresistor used
. Infrared module: IRM-3638T receiver used. Remote control: NEC TV remote control from the universal remote control app on my phone.
Motor: I bought a driver board and a 5-wire 4-phase motor

I drew the voice module incorrectly when designing the board (the pins are easy to miscount...). I could only use two wires.

If the voice module malfunctions, i.e., when the pronunciation is incomplete, you need to consider the power supply issue. I directly replaced it with a different one.
