Automatic Curtain Opener

I built a simple automation to open my curtains on a schedule. I opened a cheap smart plug and wired its output relay to a motor that pulls the curtain cord.

What Happened

It worked for two months until it fell off the wall.

• The problem: I mounted the motor with double-sided tape. The daily stress from pulling the cord pulled the tape apart.
• Result: The motor broke when it fell.

What I Learned

Double-sided tape works for sensors, but not for parts that move. The electronics worked fine, but the mounting was the failure point. Next time I’ll use screws.
