Make a Digital Voltmeter Using an Arduino - All About Circuits
This Voltmeter Ammeter was designed to measure output voltage of 0-70V / 0-500V with 100mV resolution and 0-10A or more current with 10mA resolution. It is a perfect addition to any DIY laboratory power supply, battery chargers and other electronic projects …

Measuring Current with the Arduino Measuring Current with the Arduino The Arduino's analogue input pins measure voltage (generally between 0 and 5 volts) so how do we convert current into volts? It's purpose is to 'shunt' most of the circuit current away from the ammeter which, itself, is designed to handle only a few milliAmps to

The project uses an Arduino pro mini board whose ADC feature is used along with the concept of Voltage Divider circuit to develop this Voltmeter. V RESOLUTION = 5V / 1024 = 4. 88 milli Volts. Fig. 6: Overview of ADC Channels in Arduino Uno The complete circuit diagram of the Arduino based Voltmeter is given in which the voltage to be

Arduino AC Voltmeter Project with Code and Circuit Diagram
The Arduino can accept up to 5v on a analog input. Our voltage can range as high as 20vdc in certain situations (open circuit pv voltage), so we designed a voltage divider that would provide 5v at 20v battery voltage, and less at various lower voltages.
