Putting the Arduino inside its own battery pack makes a very neat and compact self-contained unit. At the heart of the board is an ATmega328 clocked at 8MHz to reduce power consumption and fused ...

Behind the delightfully punny name, you’ll find an Arduino-compatible board the size of an AA battery. Growing up in the bad old days, you’ll remember what an epic pain in the rear-end it ...

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. The result may not be the ...

Watch the video after the jump to learn more about the EnergyShield Arduino rechargeable battery project and see it in action. Together with a 500 mA output and an on-board fuel gauge IC thats ...

for Raspberry Pi & Arduino”. The pictured shield holds a 18650 Li-Ion battery holder at the top of the circuit board, which can accommodate an ‘unprotected’ single-cell lithium-ion battery. It also ...

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. In other words, he dropped ...

The Arduino board can be powered from a standard 9V battery pack, as usual. As you may well know, Arduino’s analog inputs can be used to measure DC voltage between 0 and 5V (when using the standard 5V ...

The button-sized Curie is a single package encapsulating microcontroller, Bluetooth, a 6-DOF IMU, and battery ... a carrier board to interface with this hardware. This is where the Arduino/Genuino ...
