Little Bird Electronics posted an article about using an analog voltage reference with Arduino. This is a tool available when using an analog-to-digital converter. By setting up either an internal or ...

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 ...

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 ...

Engineers like to simplify the design process using many rules of thumb. One of my favorites is to always drive the inputs of an analog-to-digital converter (ADC) with a low impedance source. Why do I ...
