IoT and wearable devices have become essential tools in our everyday lives. From health monitoring wearables to smart home sensors, they rely heavily on battery power to function. However, optimizing ...

If you’ve got a few solar panels lying around, or even if you want some 120/230 V AC power from a few 12 Volt batteries, you’ll need a power inverter. Sure, you can drop on down to any big box store ...

If you're developing a wrist watch, a small light-following robot, or a portable weather station with Arduino, one of the best boards you can use is the Nano, and for good reason. It's pretty compact, ...

Electrical power systems engineers need practical methods for predicting solar output power under varying environmental conditions of a single panel. By integrating an Arduino-based real-time data ...

One part that I find myself using somewhat regularly in microcontroller-based experiments is the “USB power bank” that provides USB-standard 5-V DC output and offers some basic protection features.

[Trent M. Wyatt]’s CPUVolt library provides a fast way to measure voltage using no external components, and no I/O pin. It only applies to certain microcontrollers, but he provides example Arduino ...

Makers and hobbyists looking for a more substantial portable battery pack that they can make themselves, should check out this excellent DIY power bank created by Instructables user “tobychui”. Using ...

Arduino, an open-source electronic platform for fast prototyping, helps electrical engineers prototype/design their projects, with the intention that they will turn into commercial products down the ...

Most DIY tech enthusiasts have heard of a Raspberry Pi. But, like all things in the tech world, competition is inevitable. Arduino is a microcontroller used to control motors, LEDs, and interfacing ...

Arduino has unveiled a new low-code solution for product creators designing hardware for the internet of things (IoT). It also unveiled a new family of Portenta chips for a variety of hardware ...
