RGB LED (Common Anode ) (Pack of 10) RGB LED (Common Anode) makes some beautiful colors, this 10mm tri-color LED with separate red, green and blue LED chips inside! They make a nice indicator, and are fun to color-swirl. We like RGB LEDs because they color mix inside instead of appearing as 3 distinct LEDs. These RGB LEDs are Common Anode type which means you connect one pin to 5V and then tie the other three legs to the ground through a resistor. Most of the people use CA( common anode) more than CC(common cathode) because multi-LED driver chips are often designed exclusively for Common Anode and can’t be used with Common-Cathode. These RGB LEDs have four pins: one for each color and a common anode. Use this one LED for three status indicators or pulse width modulation all three and get mixed colours! If you want to use these RGB LEDs with your Arduino project, then you will need few components like resistors , jumper wires and breadboard
