Arduino’s new power management library provides developers with the tools they need to reduce power consumption, extend battery life, and enhance performance across various devices.

Arduino Measures Remaining Battery Power With Zero Components, No I/O Pin. 22 Comments ... but for the purposes of measuring battery power in a system or deciding when to send a “low ...

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… ...

DIY Arduino power bank with display and 60w power output. ... Lithium Ion battery in the form of four Panasonic 3200mAH cells connected to a 60W IP2716 based power boost and charging module.

Options to power the Arduino Nano include USB, VIN, ... The 5V pin can come particularly handy in cases when you're using a 5V supply — from a Battery Eliminator Circuit (BEC) ...

One of the great things about the Arduino is that it’s totally open source so you can make your own variations on it. Case in point, DIYer Johan Kanflo’s AAduino, which comes in at the size of ...

What do you do if even the smallest Arduino boards (or their clones) are too big for your homebrew project? If you're Johan Kanflo, you find a way to make them even smaller. His AAduino project ...

For simplicity, I used a resistive load (the original plan was to use a 4.7R resistor but I didn’t have any high power resistors to hand so I used 4 22R resistors in parallel instead giving me ...

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.
