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 ...

When developing electronic projects, the power supply is one of the most important part of whole project and there is always need of multiple output voltage power supply. This is because different ...

Adafruit has announced the launch of a new product today in the form of the VERTER power converter, which has been created to convert just about any battery pack to 5V for just $9.95 VERTER is capable ...

Recently I bought a few portable power supply devices to run my little microcontroller projects. There are countless variants of portable power supply devices that can be used to power up most ...

In this tutorial, we are going to build a Lithium Battery Charger & Booster Module by combining the TP4056 Li-Ion Battery Charger IC and FP6291 Boost Converter IC for a single-cell Lithium battery. A ...

The aim of this project (or more specifically the code), is to see how well object orientated programming (OOP) works on an embedded platform. In other words, this is a software engineer's take on a ...

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 ...

Seeeduino XIAO is the smallest Arduino compatible board from SeeedStudio’s Seeduino family. Measuring just 23.5×17.5 mm, the board is equipped with Microchip SAMD21 Arm Cortex-M0+ microcontroller and ...

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 ...

This project may be useful to someone trying to solve some of the challenges of this problem. In fact, the tap system was the most trivial part of the project while the GSM communication and battery ...
