We’ve seen [Johan]’s AA-battery-sized Arduino/battery crossover before, but soon (we hope!) there will be a new version with more MIPS in the same unique form factor! The original Aarduino ...

It only applies to certain microcontrollers, but he provides example Arduino code showing how handy this can be for battery-powered projects. The usual way to measure VCC is simple, but has ...

His AAduino project turns the already miniscule Tiny328 Arduino clone into an even smaller computing device that's about as big as an AA battery. Through creative wiring, it even fits inside a ...

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.

Behind the delightfully punny name, you’ll find an Arduino-compatible board the size of an AA battery. Growing up in the bad old days, you’ll remember what an epic pain in the rear-end it ...

Case in point, DIYer Johan Kanflo’s AAduino, which comes in at the size of a AA battery. Kanflo’s project is a wireless Arduino clone that’s meant to operate in a way that doesn’t take up ...

Denis Hennessy recently encountered a problem we've all faced: he needed some AAs for a battery-eating gizmo ... buy samples of all the batteries, build an Arduino-controlled testing rig, and ...

Last year, the Raspberry Pi Foundation surprised the hobbyist world with its RPi Zero, the smallest incarnation of its popular single-board computer. However, that has nothing on this even smaller ...

The microcontroller also delivers performance that stacks up well with an Arduino Mega but at a smaller size -- the Pinoccio only measures a couple of inches long and an inch wide.

The Arduino board can be powered from a standard 9V battery pack, as usual. As you may well know, Arduino’s analog inputs can be used to measure DC voltage between 0 and 5V (when using the standard 5V ...
