AUTOMATION IN 4 STEPS
How It Works
1
Motion Detected
The HC-SR04 ultrasonic sensor detects an object or hand nearby.
2
Lid Opens
Arduino processes the distance reading and activates the lid mechanism.
3
Lid Closes
After a short delay without motion, the lid returns to its closed position.
4
Smart & Clean
Enjoy convenient, hands-free disposal while learning practical automation.
WHY ROBOTRASH?
