This Arduino sketch sequentially turns on and off LED strips that are attached under the bullnose of each step in a stairwell. The project uses synchronous serial communication with 74HC595 shift ...

We designed an Etch A Sketch of sorts using an LED dot matrix and an analog joystick. The main purpose was to create a fun toy and learn more about circuit components in the process. Our project has ...

The Etch-A-Sketch was a toy that demanded mastery. Some grew capable of creating masterful artworks, while others struggled to do more than a jumbled mess of angry, angular lines. The inherent ...

8×8 LED Matrix modules are now widely available, and fortunately they are easy to use with our favorite Arduino microcontroller. 8×8 LED Matrix module have many applications in real life, such as ...

What was your first Arduino program? Probably an LED blinker — that seems to be the “hello world” of microcontrolllers. You probably moved on to things a little more complicated pretty quickly. At ...
