Among all the Arduino boards, the Uno is most folks' go-to choice, and for good reason. It's the perfect platform to get started with Arduino, it's capable enough to handle a wide range of tasks, and ...

Elektroniker und Bastler, die Speicherplatzprobleme mit ihrem Arduino haben, können auf andere Speichersysteme ausweichen: Neben batteriegepufferten SRAMs gibt es auch die Möglichkeit, Informationen ...

There are easy ways of getting more I/O pins for any project; shift registers, I2C expanders, or ADCs will give you plenty of pins for whatever project you have in mind. All these require extra ...

Having had such quick success making a microcontroller project using an 8pin ATtiny85 and programming it with Arduino, I though I would try a more elaborate project, one that has been on the back ...

There are two kinds of people in the world (and, no, this isn’t a binary joke). People who love the Arduino, and people who hate it. If you’ve ever tried to use a standard prototype board to mount on ...

The term “Charileplexing” is not a familiar one for many electronics hobbyists. Charlieplexing is a technique proposed in early 1995 by Charlie Allen (at Maxim Integrated) for driving a multiplexed ...

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 boards ...

This is a simple 0 to 9 counter circuit constructed using Arduino! Here, a common cathode 7-segment LED display is connected to Arduino for displaying the digits. The code (Arduino sketch) allows push ...
