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

At first glance, an Arduino library for LED control might seem superfluous, but if you are interested in nice effects, the coding for them can be a bit onerous.

– RAM: 3bytes WS2812B & Arduino Earlier we controlled LED matrixes, strips and other complex LED projects bundled with countless interconnected wires with the help of multiplexers and shift registers.

Arduino simplifies things by only using just one coding language. Here's what you need to get started with developing software for the tiny device.
