2. RGB LED Ring

For the RGB LED ring to work, you will first need to solder three wires to the bottom of the ring.

Solder red wire on the pin that reads VCC (5V power), black wire on the GND pin (ground) and orange wire on IN pin (data in).


After soldering the wires, connect them as shown on the diagram.

You will also need a 470Ω resistor, as well as a 1000uf 10V capacitor.

Place the capacitor so that the side with (-) mark goes into the ground on the breadboard.
