RGB Common Anode LED makes some beautiful colors with this 10mm tri-color LED with separate red, green and blue LED chips inside! They make a nice indicator, and fun to color-swirl. We like RGB LEDs because they color mix inside instead of appearing as 3 distinct LEDs.
These are Common-Anode type which means you connect one pin to 5V or so and then tie the other three legs to the ground through a resistor. We carry and use CA more than CC because multi-LED driver chips are often designed exclusively for CA and can’t be used with Common-Cathode.
