Introduction: Tutorial to Interface RGB Led WS2812B With Arduino UNO

This tutorial is going to teach you some basics on using Sparkfun RGB Led WS2812B with Arduino UNO

Step 1: Introduction

Description:

This is a breakout board for the WS2812B RGB LED. The WS2812B (or “NeoPixel”) is actually an RGB LED with a WS2811 built right into the LED! All the necessary pins are broken out to 0.1" spaced headers for easy bread-boarding. Several of these breakouts can even be chained together to form a display or an addressable string.

Specifications:

1. Size : 50mm x 50 mm
2. Colour display : Red, Green, Blue

3. Viewing angle: 120 degrees

4. Red: (620-630nm) @ 550-700mcd

5. Green: (515-530nm) @ 1100-1400mcd

6.Blue: (465-475nm) @ 200-400mcd

7.Description:

VCC - Input voltage 5V

GND – The common, ground, 0V reference supply voltage.

DI – Data from a microcontroller comes into this pin.

DO – Data is shifted out of this pin, to be connected to the input of another pixel or left floating if it is the last link in the chain.

Step 2: Pin Definition

Step 3: Hardware Installation

Step 4: Sample Source Code

To get the result, please download the sample source code attached below.

Step 5: Include Adafruit_NeoPixel.h Library

Click skecth then find include library and click manage library. Next, search adafruit neopixel and install the latest version

Step 6: Upload Source Code

Open the source code. Make sure com of arduino UNO and com port is same and please sellect the board is Arduino UNO.

Click upload.

Step 7: Result
