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 ...

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 ...

Arduino Mega board verlengt de tracking-tijd van een oscilloscoop tot 12 uur, bijvoorbeeld om de (ont)laadcurve van een accu weer te geven. Stel dat u een langzaam variërende spanning van een sensor ...

This code is used to display voltage and frequency measurements on an OLED display. The voltage measurement is done by using an analog input and a voltage divider circuit with resistors R1 and R2, ...

// The target MCU is an Microchip/Atmel ATmega328P, configured to behave like an Arduino Uno // The Arduometer PCB is designed to accept a Sparkfun FTDI Basic USB-UART bridge and to be programmed ...

We think it’s a great learning experience to tear back the veil of abstraction and learn a bit more about the hardware found on an Arduino board. This project is a great example. [Scott Daniels] takes ...

The ATMega328 microcontroller as mounted on the Arduino UNO board has a 10-bit AD converter. Let’s use its function analogRead to measure some voltages with. How can we improve the accuracy of the ...

Makers, developers, and hobbyists looking for a way to measure both voltage and current simultaneously may be interested in a new Arduino project published on the official Arduino blog. This project ...

Abstract: The Smart Energy Meter represents a significant improvement in automated billing systems, offering better efficiency, speed, convenience, and reliability compared to conventional meters. In ...
