This project uses a high-brightness, three-color LED in combination with a rotary encoder. Turning the rotary encoder changes the color displayed by the LED.
The LED lamp is interesting because it has three LED lights in one four-pin package. The LED has a common-cathode arrangement, meaning that the negative connections of all three LEDs come out of one pin.
