4. Assembly Instructions
This section provides general guidance for assembling both kits. Detailed, step-by-step instructions with component identification are provided in the physical manual included with your kit.
4.1 General Soldering Tips
- Ensure your soldering iron tip is clean and properly tinned.
- Heat both the component lead and the PCB pad simultaneously.
- Apply a small amount of solder to the heated joint, allowing it to flow evenly.
- Remove the solder and then the iron, holding the component steady until the solder cools.
- Check for cold joints, solder bridges, or insufficient solder.

5. Setup
5.1 Powering the Ultrasonic Ranging Alarm
The ultrasonic ranging alarm typically operates via a 5V power supply. Connect a compatible 5V power source to the designated input port on the device. Ensure the power switch is in the 'OFF' position before connecting power, then switch to 'ON' to activate.
5.2 Powering the LED Desk Lamp
The LED desk lamp offers two power supply methods:
- 5V Power Supply: Connect the lamp to a standard 5V USB power adapter using the provided cable.
- Battery Powered: The lamp includes a built-in rechargeable battery. Ensure the battery is fully charged before initial portable use. Connect to a 5V power supply to charge the battery.

6. Operating Instructions
6.1 Ultrasonic Ranging Alarm Operation
Once powered on, the ultrasonic ranging alarm will begin real-time distance measurement. The measured distance will be displayed on the 3-digit digital tube.
- Distance Display: The digital tube shows the distance in centimeters (cm).
- LED Indicators: Corresponding LED lights will illuminate to provide a visual indication of the measured distance range (e.g., 30cm, 60cm, 90cm, etc.).
- Alarm Function: Use the two control buttons (S1, S2) to set a specific distance threshold for the alarm. If the measured distance falls below this set threshold, the device will emit an audible warning beep.
- Disabling Alarm: To disable the alarm function, set the threshold distance to 0 using the control buttons.

6.2 LED Desk Lamp Operation
The LED desk lamp is designed for versatile use with adjustable features.
- Power On/Off: Use the power button located on the base to turn the lamp on or off.
- Adjustable Brightness: The lamp features adjustable brightness levels. Use the designated control (e.g., a dial or button) on the base to cycle through or select desired brightness settings.
- Flexible Gooseneck: Adjust the flexible gooseneck to direct the light precisely where needed.
- Phone Holder: The lamp base includes a built-in phone holder for convenience.
