NeoPixels / WS2812B LEDs With Raspberry Pi Pico Tutorial

Introduction

In this article, we will be discussing how to set up ws2812b LEDs with raspberry pi pico. Introducing the WS2812B LED. The WS2812B is an addressable RGB LED. That means you can control the colour of each individual LED. The WS2812B is also known as the NeoPixel. Follow these simple steps and you’ll have your LEDs up and running in no time!

In this tutorial, we will be using the Raspberry Pi Pico as our microcontroller. The Pico is a great choice for this project because it is small, cheap, and easy to use.

Required components

You will need the following materials for this project: –

  • Raspberry Pi Pico
  • WS2812B LED
  • Breadboard
  • Jumper wires

What is Raspberry Pi Pico?

Raspberry Pi Pico is a low-cost, high-performance microcontroller board developed by Raspberry Pi Foundation. It was launched in January 2021. The board is based on the RP2040 microcontroller chip developed by Raspberry Pi Foundation. Raspberry Pi Pico can be used for various applications such as robotics, the internet of things (IoT), and embedded systems.

What are ws2812b LEDs?

The WS2812B is also known as the NeoPixel. These LEDs are commonly used in applications such as RGB backlighting, colour-changing effects, and lighting control systems. One of the benefits of using WS2812B LEDs is that they offer a wide range of colours and can be controlled individually, which allows for a wide range of lighting effects.

Ws2812b LEDs are a type of SMD LED that is often used in LED strips and strings. They are known for their bright colours and high intensity.

The WS2812B is also chainable, which means that you can control multiple WS2812Bs with a single signal wire. In this project, we will be using the Raspberry Pi Pico to control a WS2812B LED.



How WS2812B LEDs Work

The WS2812B is an integrated light-emitting diode (LED) and driver circuit. The device is designed for use in3528 and 5050 SMD LEDs. It is an “intelligent control LED light source” that contains a control circuit and an RGB chip integrated into a single 5050 SMD component. The control circuit built into the WS2812B LED allows it to be controlled with a very simple interface, such as a raspberry pi pico or Arduino etc. microcontroller.

The WS2812B has 3 pins. The first two pins are for power. The second two pins are for data. The data pin is what we will use to control the LED. The WS2812B LED is controlled by a microcontroller.

Schematics Diagram – ws2812b LEDs with raspberry pi pico

let’s take a look at the circuit diagram. The Pico is going to be the core of our circuit. It will control the LED. The LED is connected to the Pico through the data pin. The power and ground pins of the LED are also connected to the power and ground pins of the Pico.
