jumper wires as needed

RGB LEDs emit light in various colours. They package three LEDs of red, green and blue into a transparent or
semi-transparent plastic shell, and have four pins. The three primary colours can be mixed into various colours
by brightness. The LED brightness can be adjusted with PWM. The Raspberry Pi
