1. Product working voltage DC=5V
2. The long pin of the capacitor LED is the positive pole, and the short pin is the negative pole
3. When soldering the IC, pay attention to the direction. The dots on the IC surface are in the same direction as the dots on the IC silk screen on the PCB board.
4. The resistance value of the resistor is measured by a multimeter or the color ring on the surface of the resistor
5. Pay attention to soldering the LED in the last step
