Positive and Negative Pole Identification
- Identify by pins: The longer pin is the positive pole, and the shorter pin is the negative pole.
- Identify by head: The smaller head is the positive pole, and the larger head is the negative pole.
- Use a multimeter in diode mode to measure: When the LED is conducting and emitting light, the red probe indicates the positive pole, and the black probe indicates the negative pole.
