Diffused 5mm tri-color LED with separate red, green and blue LED chips inside! Nice indicator, and fun to color-swirl. 60 degree viewing angle. We like diffused 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 ground through a resistor. We carry and use CA more than CC because multi-LED driver chips (such as the TLC5940/TLC5941) are often designed exclusively for CA and can't be used with Common-Cathode.

Jargon buster
Plain-language definitions for the technical terms used above.
- common-anode
- A wiring style for multi-colour LEDs where the positive side is shared and each colour channel is controlled on the negative side. This matters because common-anode and common-cathode LED strips are not interchangeable without a suitable driver.
- LED
- A light-emitting diode is a small electronic component that lights up when current flows through it in the correct direction. In this kit, LEDs create the flashing effect, so polarity and correct soldering matter for the project to work.
- LED driver
- An LED driver is a control chip or circuit that supplies and switches power to LEDs. For a display board, it reduces the number of microcontroller pins needed and handles tasks like lighting the right segments and adjusting brightness.
- RGB
- Short for red, green and blue, usually referring to an LED that can mix those three colours. It matters because controlling an RGB LED teaches how separate outputs combine to create different colours.
- Torque
- A twisting force that causes something to rotate, usually measured in newton-metres or kilogram-centimetres. It matters when choosing motors, servos, gears, and tools because higher torque is needed to lift heavier loads, turn larger wheels, or move mechanisms without stalling.
