1. RGB LED ring

For our first component, we will go with the new LED Ring.
First, you will 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).*

  • You can use any wire color you have available instead of orange.

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.
A capacitor will be placed after we have set everything up.
