Quick Tips:
∑ Stable Mounting: Secure the ultrasonic sensor firmly to prevent inaccurate readings caused
by sensor movement.
∑ Cable Management: Neatly arrange and tape down wires to avoid disconnections during
operation.
∑ Battery Check: Use fully charged batteries to ensure the servo motor operates smoothly.
Weak batteries may cause the lid to malfunction.
∑ Testing Thresholds: Adjust the detection distance threshold in the code if the lid opens or
closes unexpectedly.
Troubleshoot:
Lid Doesn't Open/Close:
◦ Ensure the ultrasonic sensor connections (Trig and Echo) are correctly wired to the
Micro:bit.
◦ Verify the servo motor is connected to the correct pin (P2) and receiving power.
◦ Check the battery pack for sufficient charge.
Inaccurate Detection:
◦ Make sure the ultrasonic sensor is aligned properly and not obstructed by dustbin edges.
◦ Adjust the sensor’s angle for better object detection.
Servo Motor Jitter:
◦ Reduce jitter by adding a short delay between servo movements (e.g., pause 100 in the
code).
◦ Ensure the servo motor is compatible with the Micro:bit and can handle continuous
rotation.
WiFi Module Not Responding (Optional):
◦ Double-check UART connections (P13 for TX, P14 for RX) and verify that the module is
powered correctly.
