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 ...

Discover how you can build a professional digital multimeter using Arduino that measures up to 24V DC voltage, checks resistance, conducts diode testing, and performs continuity tests. This ...

You can create a release to package software, along with release notes and links to binary files, for other people to use. Learn more about releases in our docs.

This project measures real-time voltage and current from a DC load using an ACS712 Hall-effect current sensor and an analog voltage divider connected to an Arduino. The data is read by the Arduino’s ...

The presented solution for measuring voltage of Zener diodes using Arduino is completely new and original. The circuit uses LM317 as a constant current source and the whole measurement process is ...

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 ...

Abstract: The paper presents a new low-power interface circuit based on a voltage divider consisting of a reference resistor, a resistive sensor and a microcontroller equipped with an ADC. The novelty ...

[Lauri Pirttiaho] from the [Swiss Knife of Electronics] channel explains how to simplify your resistive divider keypad design on Hackaday.io. The usual method involves building a resistive ladder that ...
