15 May: SK28A – RGB LED Mood Lamp

This project uses SK28A to show the RGB LED. The RGB LED is a special type of LED which can emit three coloured lights, which are the Red, Green and Blue, hence the RGB acronym. When one of these colours mixed together it will give you another new colour. By using the microcontroller’s PWM channels to drive the LED, you can control the intensity of each colour which can give you many shades of different colours.
