There is so much you can do with WS2812B addressable LEDs once you learn the basics. However, always remember to choose the correct micro controller (or arduino board) based on the RAM requirements of ...

Learn how to control and blink multiple LEDs using the MAX7219 driver with Arduino. A simple guide for beginners in ...

This is tutorial number 1 from our series of Arduino tutorials and in this part I will talk about blinking an LED using the one already available on the Arduino Uno board or using an external LED to ...

Description: Using an Arduino or a micro controller we can generate cool looking patterns with an led strip with addressable LEDs. In this case I'm using an Arduino uno (clone board) and a strip of ...

At some point, he switched from LEDs to Neopixels, and dug deep into addressable LED technology. For instance, he demonstrates Neopixel power measurements and current consumption calculations.

The design would need so many LEDs that it crossed the limit that an Arduino can address, thus there were two Arduinos to control the whole.
