Package Contains:

• Arduino Nano – 1
• USB Cable – 1
• Ultrasonic Sensor – 1
• Servo Motor – 1
• Breadboard – 1
• Breadboard Power Module – 1
• Jumper Wires (Male-Male & Male-Female) – 1 set

Working Principle

The ultrasonic sensor detects hand proximity and sends a distance signal to the Arduino Nano. The Arduino processes the reading and triggers the servo motor to open the lid. When the hand is removed, the lid closes automatically — a simple, hygienic, and educational automation project.

Implementation

• Connect Ultrasonic: VCC, GND, Trigger → D2, Echo → D3.
• Connect Servo: VCC, GND, Signal → D9.
• Wire the breadboard power module to supply stable 5V to modules.
• Upload the Arduino sketch (sample code available on the project page).
• Mount the servo to the dustbin lid and test proximity-triggered opening/closing.
