Soldering NeoPixel

Solder four NeoPixels in a strand of four lights. The light wire hangs easily on a tree branch.

Soldering NeoPixel

Properties

Set these properties in the Arduino IoT Cloud

Properties

Circuit

Data sent from pin 6, across a 220ohm resistor, to three strands of lights. Power from VCC, over the 1,000uF capacitor, and to ground. Three strands connected: positive to positive, and negative to negative. Extra wiring and buttons towards my thumb is extraneous. It was left over from experiments.
