So, what do you do when your Arduino project needs to operate in a remote area or as a portable device? There are LiPo battery shields available, and although they may work well, recharging ...

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.

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 Aardu… ...

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.

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 ...

Kanflo’s project is a wireless Arduino clone that’s meant to operate in a way that doesn’t take up a lot of battery juice, so it’s pretty low power.

Arduino enthusiasts and makers searching for a new project to keep them busy this weekend may be interested in a new DIY Arduino Nano multimeter ...

This Arduino-compatible board fits neatly into a AA battery slot. Kanflo opted for this form factor to create a self-contained radio node that supplies its own power.

For this project, its creator used an Arduino Pro mini, a cellphone battery, a few other tech parts, and an old digital watch that was big enough to hold the PCB board.
