Smart curtain control

"Little Wang—Open the curtains!" The motor rotates forward, and the curtains are opened.
"Little Wang—Close the curtains!" The motor rotates backward, and the curtains are closed.
This is the voice command for controlling the curtains, using the HLK-V20 voice recognition module. The main controller is Liangshanpai; other components can be purchased from LCSC. The motor is a 28BYJ-48 stepper motor I found (I couldn't afford the recommended motor; I only had a 50 RMB coupon, and LCSC didn't sell it yet—I'm a freeloader, lol). I redesigned the PCB to be the same size as Liangshanpai for a better look. Since the microphone, speaker, and motor will definitely require wiring, I only left one interface.
I only implemented voice control; other functions have hardware components, but I didn't write the program. First, I don't know how to program; second, voice control is already quite intelligent. ![Curtain.png]
