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. The ...

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 requires ...

This Arduino based battery discharge monitor aims to provide an estimation of the capacity left in the battery by measuring and plotting its discharges. This Arduino based battery discharge monitor ...

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 available. Ignoring the shiny packaging and its ...

A Swedish software engineer — Johan Kanflo — has made a wireless Arduino clone called AADuino, which is the size of an AA battery. Kanflo explains that the AADuino has an onboard RF module, which fits ...

Connector to add external battery to real-time clock (RTC) inside Renesas MCU (MCU RTC power pad held to 5V rail on Minima) Secondary (wireless) processor: 240MHz 3.3V dual core 32bit Espressif ...

Trying to figure out the capacity left in a battery based on only its voltage is difficult. The equivalent-series-resistance (ESR) of the battery makes the cell’s voltage a function of the current ...
