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.

He set up an Arduino Uno to count the pulses using edge detection. This allowed for a reliable count which would serve as the timebase for a simple 24-hour clock.

Running out of GPIO pins? Learn how to connect multiple buttons to just one Arduino pin using clever wiring and resistor techniques. Perfect for compact projects, keyboards, or when using small ...

His offering uses the Arduino Uno, but there are several other hardware options covered as well. The firmware makes use of the serprog-duino library which was crafted at writing to flash memory chips.

The Dr.Duino Pioneer is compatible with any Arduino Uno motherboard, and you can control it using the C programming language.

Others contain wireless networking gear. Arduino also offers shields that focus on more specialized tasks, such enabling a Uno chip to be used as an industrial robot’s motor controller.

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 ...

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 ...
