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… ...

You might think that there could be no form factor that has not as yet had an Arduino fitted in to it. This morning a new one came our way. [Johan Kanflo]’s AAduino is an Arduino clone with a… ...

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 ...

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 robot. Understanding your battery's status is ...

⚠️ When using a direct connection, keep in mind that your microcontroller and/or PC is directly connected to a huge battery. It is very easy to create a short circuit that kills your microcontroller, ...

The EnergyShield Arduino rechargeable battery has been created by Nightshade Electronics and has three main internal functions including a circuit to boost the battery’s nominal voltage of 3.7V ...

Born from Johan Kanflo's mind, the AAduino, so named because of its size, can, almost, conveniently fit inside a 3x AA battery holder for maximum space footprint efficiency.

The LabView Interface for Arduino was used in the design of the real-time battery monitoring system. This necessitates the use of an efficient battery monitoring system that takes into consideration ...
