Hardware
The first step,step is to hook up your microcontroller to your lights. To do this weWe only need three wires, two for power, and one for data.
Follow these steps:
- Cut off one end of three jumper wires and strip about 5mm of insulation from each wire.
- Solder one wire to each of the three pads on the NeoPixel strip: 5V, GND, DIN.
- Plug the other end of each wire into the NodeMCU as follows: 5V to the VIN pin (+), GND to any GND pin (-), DIN (Data In) to the D1 pin.
- If you want to chain together multiple strips, connect the positive and negative to the other strips, and chain DO (Data Out) to DIN (Data In)
