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 ...

In this project, we create a joystick-controlled laser by connecting two servos to a joystick and using this setup as a pan-and-tilt controller for a laser pointer. The following is excerpted from the ...

My daughter likes buttons. She's learning letters. I was bored over winter break and had these parts laying around... so I built her a "Button Box" based around an Arduino. Open source, hackable, and ...

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 ...

Arduino Micro has some extra leds that it is tricky to programme. Like almost all Arduinos, has a built-in led – the green one on the left in the photo. And it has a pair of yellow leds – called TX ...

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 ...

Every week the Hackaday tip line receives an email about a new dev board. The current trend is towards ARM devices, and only once have we seen an x86-based device. Today that count went up to two.

Arduino enthusiasts looking to incorporate Nixie Tubes in their next project may be interested in a new Arduino Nixie Tube SHIELD which has been created by Marcin Saj based in Poland. The Arduino ...
