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 ...

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 adhered to ...

The nano sensor interface presented below is a microcontroller-based universal sensor interface with a power-saver mechanism. The idea, centered around an Arduino Nano (v3) microcontroller, was ...

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 ...

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 ...

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 ...

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 ...

Arduino enthusiasts may be interested in a new single pixel scanning camera which is powered by an Arduino Uno combined with a TCS34725 sensor available from online stores such as Adafruit. Created by ...
