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 ...

This is a simple communication example between arduino and processing control panel. By cliking into the panel you can see that your Arduino uno built in led turn on and the counter increase. If you ...

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 ...

I have spent at least an hour almost every day since the 80’s advancing my knowledge in electronics. Recently I brushed up my knowledge on LED fading secrets and attained something pleasant. Now, I’d ...

The Etch a Sketch toy has gone more or less unchanged for over 60 years, but if you’re handy with a soldering iron you can build an upgraded version that swaps aluminum powder for glowing LEDs. You’re ...

That’s it, and the built-in LED of my board is indeed blinking now. That was relatively easy to get started, and it may boost the productivity of people preferring to work from the command line ...
