[Trent M. Wyatt]’s CPUVolt library provides a fast way to measure voltage using no external components, and no I/O pin. It only applies to certain microcontrollers, but he provides example Ar… ...

Each of the 14 digital pins on the Arduino Uno can be used as an input or output, using pinMode(), digitalWrite(), and digitalRead() functions. They operate at 5 volts. Each pin can provide or receive ...

While a Raspberry Pi is a full-fledged computer that can do more complex things than an Arduino microcontroller, it's not the best choice for every project.

The official Arduino team has this week revealed more details about the new Arduino UNO R4 development Board which will be officially launching in a few months time during May 2023.

The vertsatile Uno Rev3 is capable of more than just a board for experimental and education projects ...

Low-cost thermal camera built using Arduino 7:59 am August 11, 2023 By Julian Horsey In the realm of DIY electronics, the Arduino UNO has emerged as a versatile platform for a myriad of projects.

The beautiful part of this is that Trollduino occupies the same footprint as an Arduino Uno and is even pin-compatible with the microcontroller board, or at least sort of.

Arduino has announced the new UNO R4 board family for prototyping and learning. The new models feature a faster microcontroller, a USB-C connector, improved power, Wi-Fi and Bluetooth LE, and more.

Using motion detectors and an Arduino you can trigger lights, fans, or even an pneumatically controlled cleaver-wielding clown to help add your house to the “if you dare” list.

The successor to the original BeagleBone, the Black comes with faster hardware, lower power requirements, and a surprising $45 price point.
