While newer Arduinos and Arduino compatibles (including the Hackaday.io Trinket Pro. Superliminal Advertising!) either have a chip capable of USB or rely on a V-USB implementation, the old fogies o… ...

We all know how fireworks are lit. It is simple, hold the flame of a lighter close to its wick and the gunpowder does the rest of the magic. However, in this post, I am going to explain how to do the ...

The Arduino Wire library is a core aspect of Arduino's integrated development environment, or IDE, and is a must-have if you're using sensors or extra microcontrollers in your project.

Bottom: Drill a hole in a second coupling for a bundle of wires leading to an Arduino Uno microcontroller. 2) WIRE UP Connect the socket and computer fan to 5-volt relays, and link them to the ...

The long-awaited Arduino Due just hit the market, replacing the 8-bit, 16 MHz brain of the popular Uno microcontroller prototyping platform with a 32-bit, 84 MHz processor, while augmenting inputs ...

According to datasheets, the absolute maximum source current per I/O of Arduino Uno is 40mA, and 20mA is the good design value. A textbook red LED has a forward voltage (Vf) of 1.8V and a forward ...

A speed-controlled dc-motor chopper drive of wire- feed mechanism implemented by Arduino-Uno board is presented in this paper. This drive system is characterized as high static and viscous frictions ...

Creating a video signal from a computer, a job that once required significant extra hardware, is now a done deal with a typical modern microcontroller. We’ve shown you more NTSC, PAL, and VGA… ...
