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 ...

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 ...

[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 ...

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.

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 ...
