1. Is this RGB LED common anode or cathode?
- This RGB LED is a common cathode. If the LED lights up with the red tip on the longest lead and the black tip on one of the other leads, you have a common anode RGB LED. You have a common cathode, if the LED lights up with the black tip on the longest lead and the red tip on one of the other leads.
2. How do you use common cathode RGB LED?
- To turn on a common cathode RGB LED, connect its common terminal to the power source's negative terminal. Connect the RED colour terminal to the positive terminal of the power source to turn on the RED colour. It will also function in the same way as a standard anode RGB LED.
3. What is the common terminal of a common cathode RGB?
- Cathode refers to the negative terminal. In this type, all the cathode terminals of the internal colored LEDs (red, green, and blue) are connected to the cathode terminal of the RGB LED as shown in the figure.
4. How do you determine the negative leg of an RGB LED?
- If the LED has two leads with equal lengths, you can inspect the metal plate inside the LED. The smaller plate represents the positive (anode) lead, while the larger plate represents the negative (cathode) lead.
5. What is common cathode LED?
- Common-cathode RGB LEDs are powered by two separate power supplies, one for the red LED and one for the blue and green LEDs, with ground serving as a common reference. One supply is dedicated to the red LED, while the other supplies both the blue and green LEDs.
