Step 26: Identify LED Polarity

Identify the positive (anode) and negative (cathode) leads of the LED. The leads must be installed correctly for the LED to function. Four methods are provided:

1. Lead Length: The longer pin is the positive (anode) lead; the shorter pin is the negative (cathode) lead.
2. Internal Case Structure: The negative (cathode) lead is typically thicker/bigger inside the plastic case than the anode lead.
3. Plastic Case Edge: The negative (cathode) lead is usually nearest the flat edge on the plastic case.
4. Testing: Use a 3V battery or multimeter. The positive (anode) lead connects to the positive terminal, causing the LED to light up (briefly, less than 0.5 seconds).

Note: If the flat edge indicator disagrees with other indicators (like lead length), prioritize the other indicators. For example, if the flat edge contradicts the lead length, use the lead length to determine the cathode.

Image Description: Illustrates the different methods for identifying LED polarity: shorter pin (negative/cathode), thicker/bigger metal part (negative/cathode), and flat edge (negative/cathode).
