Arduino Battery Monitor: A Comprehensive Guide Powering your Arduino projects often relies on batteries, whether it's a simple 9V powering a small LED circuit or a more complex LiPo battery powering a ...

How long can you keep an Arduino circuit running on three AA batteries? With careful design, [educ8s] built a temperature sensor that lasts well over a year on a single charge of three 2250 mAH rec… ...

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.

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.

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, on the other hand, offers prototyping boards not tailored for in-the-field deployments. Also, the boards are not specifically designed for ultra low power operation required for long-lasting ...
