Canadian electronics geek and nascent YouTuber [Technoyaki] wanted to measure 20 volt signals on his Arduino. One might typically use a voltage divider to knock them down to the 5 volt range of the ...

Voltage division is not just about ratios; it’s about control, clarity, and purpose. This little guide explores precision voltage dividers with quiet confidence, and sheds light on how they shape ...

[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 ...

This file type includes high-resolution graphics and schematics when applicable. It's a common challenge to measure voltages that exceed the operating voltage of the ADC used as part of the ...
