Introduction
Connect a Crazy Circuits NeoPixel to a Bit Board and control it with code.
We'll explore how to control an RGB LED (a "NeoPixel") for a bit more color from our LEDs.

We'll use Maker Tape to connect the NeoPixel to the Bit Board on a LEGO baseplate.
-
To connect the NeoPixel, one side goes to Ground (GND) and the other side to 3.3v
-
We'll then connect the center pin labeled DI (for Digital Input) to Pin 0, which will control the NeoPixel.
-
A NeoPixel is a "Smart LED" which is actually three LEDs (a red, green, and blue LED).
-
You'll notice the Ground on the Bit Board (as well as the NeoPixel and other Crazy Circuits components we'll use) is color coded White.
-
The 3.3v hole on the Bit Board is labeled and is actually two holes right next to each other on the Bit Board. (There is a small line showing the connection between them.)

We're going to load the following code for our NeoPixel ROYGBIVPWB program: https://makecode.microbit.org/_99bLT5gvm...
-
After setting up our NeoPixel we'll go through all of the listed colors; red, orange, yellow, green, blue, indigo, violet, and then purple, white, and black (which is off!)
-
-
-
Once the code is loaded it should start running immediately.
-
You can power the micro:bit via the USB cable you used to load the code or you can use a battery pack plugged into the Bit Board.
-
You'll see the NeoPixel cycle through red, orange, yellow, green, blue, indigo, violet, then purple, white and black. (Black is off!)
