How to Identify LED Anode and Cathode - 10 Effective …
2024年8月1日 · If the LED lights up, the probe connected to the longer lead is the positive (red) probe, indicating the anode, and the other probe connected to the shorter lead is the negative (black) probe, indicating the cathode. If the LED …
Light-emitting diode - Wikipedia
LEDs are made in different packages for different applications. A single or a few LED junctions may be packed in one miniature device for use as an indicator or pilot lamp. An LED array may include controlling circuits within the same package, which may range from a simple resistor, blinking or color changing control, or an addressable controller for RGB devices. Higher-powered white-…
