In this tutorial, we’re going to wire up a servo to the cloud so that you can control it remotely by setting a variable. This will allow you to set the position of the servo from anywhere online.

You will need

• Arduino Nano 33 BLE Sense
• Breadboard
• Jumper Wires
• A Neopixel / WS2812 LED Strip, Ring or Matrix

Recognizing LED Strips and Rings

Neopixels are individually addressable LED pixels. Neopixels come in a variety of shapes and sizes

• Rings are in 12,16,24, and 60 pixel options
• Strips - variety of densities (typically 30 per meter and 6 per meter) in 1m + 5m lengths, can be extended or cut to desired length. Generally waterproofed too.
• Sticks (typically in an 8 pixel group)
• Individual pixels (Jewels - cluster of 6, Individual - single addressable) can be wired and chained into a group - work like reconfigurable strips.
• Matrixes - grids of neopixels typically in 4x8 and 8x8 arrangements.

The good news is there’s one way to wire (only one pin required for communication), one library for all varieties and the code to interact with them is standard across all five types of neopixel.
