Here is a useful circuit for Arduino lovers and experimenters. It is a simple digital voltmeter, which can safely measure input dc voltages in 0 to 30V range. The Arduino board can be powered from a ...

Also keep an eye on the self-consumption of the DC voltmeter used with the setup (for me, it’s around 20 mA). It’s almost been six weeks since I’ve looked at an Arduino-based DC DVM concept, but ...

This collection of hardware is a diy voltmeter. It can measure up to 17V ... The LTC2400 ADC board is used to make the measurements, with the Arduino processing the output and taking care of ...

[Jim] reasons that it’s a chip that’s easy to repurpose should his students want to build something like a breadboard Arduino, for example. The voltmeter has a fixed measurement range from 0 ...

Arduino enthusiasts and makers looking for ... If you’d like to see more of his work, including the voltmeter he based this off. Watch this video on YouTube. Disclosure: Some of our articles ...
