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 Arduino 101 has the same dimensions as the Arduino Uno, and the pins are compatible. You can stick shields designed for the Uno on the 101. While the optimum voltage for the 101 is 3.3v, 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 ...
