Product Overview:
After welding the eyes of the worm, we can test the function of the circuit board, put the 20mm button cell into the battery box with the front facing up. If the light is dim, you should see the LED light on, if not, please cover the sensor with your fingers for testing.
If the worm's eyes do not light up, please don't worry! Start with some simple questions, check your solder joints to ensure that your components are well connected to the circuit board. Solder should flow into the circuit board and do not bounce around the component pins, also check to make sure that the direction of the transistor and LED lamp is correct.
