Arduino Smart Trash Can Lid | Ultrasonic Sensor and Servo Motor Automation (Tinkercad Simulation)
In this Arduino project, we build a Smart Trash Can Lid that opens automatically when your hand is detected and closes a few seconds after the hand is removed — using an Ultrasonic Sensor and Servo Motor inside Tinkercad.
When an object (like your hand) comes close to the sensor, the servo motor opens the lid. When the object is removed, the lid automatically closes after a short delay.
This project is a great way to learn about ultrasonic distance measurement, servo motor control, and smart automation with Arduino!
