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 ...

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 ...

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 ...

The table shows the pin configuration of the Arduino UNO–based robotic arm. The red (VCC) wires of all servos are connected to the breadboard positive rail, and the brown/black (GND) wires are ...

Arduino shields are modular circuit boards that piggyback onto your Arduino to instill it with extra functionality. Want to connect your Arduino to the Internet and post to Twitter? There’s a shield ...

Arduino doesn’t have the cultural cachet of its fellow single-board player Raspberry Pi, but it’s arguably more popular for ...

Before I start talking about this really cool thing called Arduino (Italian for "good friend"), let me say a few things about the fascinating subject of physical computing. Physical computing has been ...

Shift-out: again? Yes, shift-out registers again, now daisy-chained! But let me write down a short foreword. As probably occurs for most of the subjects, especially those related to the Arduino board, ...
