Reboot your Pi for the changes to take effect, and then proceed with the instructions. Press ctrl-X to save the file and then, when prompted, type Y and press enter. In the file that opens, add the following two lines (anywhere should be fine): hdmi_force_hotplug = 1 In the Terminal enter the following: $ sudo nano /boot/config.txt

If this happens, you need to add two lines to the config.txt file. The pin used to control the strip may conflict with audio playback, so the pixels can go crazy and not work properly. The WS2812B data pin should be controlled by the Pi’s GPIO18, because that’s the GPIO used by the neopixel node. With your Pi shutdown, follow the next schematic diagram to wire the WS2812B RGB LED strip to your Pi. You can use the preceding links or go directly to /tools to find all the parts for your projects at the best price!

For that you’ll need the following parts: In this project we’ll be controlling the WS2812B addressable RGB LED strip.

Finally, you’ll have a “Clear” button to unlit all the LEDs on the strip.

The application also allows you to display a moving rainbow effect on the strip.

You can select the strip color either by using the color picker or a drop-down menu with preset colors.

In the application, you can select individual LEDs and set its color using a color picker.

The addressable RGB LED strip will be controlled using the neopixel node that you need to install.Here’s some important aspects about the Node-RED application built in this project: I recommend that you download my course: Build a Home Automation System with Node-RED, ESP8266 and Arduino. If you like home automation and you want to learn more about Node-RED, Raspberry Pi, ESP8266 and Arduino. You need Node-RED installed on your Pi and Node-RED Dashboard.You should have the Raspbian operating system installed in your Raspberry Pi – read Installing Raspbian Lite, Enabling and Connecting with SSH.You should be familiar with the Raspberry Pi – read Getting Started with Raspberry Pi.

So, in this project we’re going to show you how to build a web application with Node-RED and Raspberry Pi to control an addressable RGB LED strip to make your life simple. However, controlling these kind of strips it’s not always easy. Addressable RGB LED strips are just awesome! You can control each individual pixel of the strip, allowing you to produce beautiful effects.
