The data is sent through the serial and the Arduino codes reads and parses this data. The actual hardware part that gives you the light is based on three TIP120 NPN Darlington transistors, each ...

* This sketch shows you how to drive a 12V RGB LED strip using a TIP122 Darlington transistor. * The sketch makes the strip RGB LEDs to show random colors. * This is done by producing random PWM ...

It requires a microcontroller to run NeoPixel LED Strip, and Arduino is very commonly used with NeoPixel, so here we will learn to Interface NeoPixel LEDs with Arduino.

In this tutorial, we are going to look at how to interface RGB Neopixel LEDs with an Arduino. We will be interfacing the WS2812B LEDs which are also known as NeoPixel.
