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 ...

The primary functions of the box are handled by an Arduino Nano; which runs the trivia game and provides user interaction via a 16×2 LCD, three push buttons, and a buzzer.

This morning a new one came our way. [Johan Kanflo]’s AAduino is an Arduino clone with an onboard RF module that fits within the form factor of an AA battery.

Arduino-fanciers Oomlout have put together a neat control box for the popular prototyping board, complete with five potentiometers and three switches. There's also a software… ...

Behind the delightfully punny name, you'll find an Arduino-compatible board the size of an AA battery.

Yes in what must be the silliest maker project we’ve featured so far, the Giftduino is simply a box that plays a jingle and displays a simple message when you open it. And, well, that’s it really.

Arduino developers and hobbyists looking for a portable battery shield to powered their projects might be interested in a new shield called the EnergyShield Arduino rechargeable battery.

Measuring Battery Capacity With an Arduino Denis Hennessy recently encountered a problem we've all faced: he needed some AAs for a battery-eating gizmo, and he was overwhelmed by the choices ...

An amusing aspect of the board is how Kanflo attached battery terminals, including a spring, on the board itself. This allows the AAduino to slot into the battery slot like a regular battery.

A Swedish software engineer makes a wireless Arduino clone called AADuino. The system fits neatly within the form factor of an AA battery.
