This projects original code and schematics were from Indian Lifehacker though I did not like some functions so I added some things and edited the code

EXPANDED TECHNICAL DETAILS

Automated Waste Management

This project creates a hygienic, touch-free waste bin using an Arduino and ultrasonic sensing.

  • Motion-Triggered Lid: An HC-SR04 ultrasonic sensor is mounted on the front. When it detects an object within 20cm, the Arduino rotates a servo motor 90 degrees to lift the lid.
  • Precision Timing: The lid remains open for 5 seconds before closing automatically, reducing the spread of germs in public or household environments.

Energy Optimization

  • Sleep Mode Logic: The firmware includes a low-power mode between sensor pings, allowing the system to run on a standard 9V battery for several weeks.
