6. Connect the Components:
Ultrasonic Sensor:
◦ Trig pin Æ Micro:bit P0.
◦ Echo pin Æ Micro:bit P1.
◦ VCC Æ Micro:bit 3V.
◦ GND Æ Micro:bit GND.
Servo Motor:
◦ Signal Æ Micro:bit P2.
◦ VCC Æ Micro:bit 3V.
◦ GND Æ Micro:bit GND.
WiFi Module (Optional):
◦ Connect to Micro:bit via UART (P13 for TX, P14 for RX)
7. Test the Dustbin:
Power the Micro:bit using a battery pack.
Place your hand or an object near the ultrasonic sensor:
◦ The lid should open when the object is detected.
◦ The lid should close after a short delay.
8. Final Touches:
Decorate the dustbin to make it visually appealing.
Secure all components with tape or glue.
Test multiple scenarios to ensure reliability.
