Controlling Outputs - Neopixels

In this section, we’ll look at a bunch of ways to control, adjust and adapt outputs from your microcontroller.

We’ve already looked at one type of outcome, visible light produced with LED’s, in section 1 and 2. Now, we’ll look at programming LED strips like the Neopixel

Light

Neopixels are programmable LEDs and they only need one pin to communicate. Way better than a whole load of individual RGB Leds and much easier to prototype with…
