Welcome to our blog post on interfacing the WS2811 (5V) RGB LED strip with Arduino! In this guide, we will walk you through the process of connecting and controlling WS2811 LED strips using an Arduino ...

Arduino Schematics uploading to the Arduino After downloading the Source Code and Schematics is built, connect the Arduino to the computer using the UBS type-B cord. Open the source code within the ...

Learn more about Arduino UNO R4 WiFi's world, create stunning LED Matrix animations, and explore a universe of Arduino projects.

The Arduino can just increment the counter up to the appropriate LED. The Arduino then controls the state of the LED using the active high enable line from the column multiplexer chip.

You could put the Arduino in deep sleep, if you wanted to and that LED will still blink. With a little work, you could probably adapt this idea to any number of circuits out of the 555 playbook ...
