Arduino 4 Channel Voltmeter Circuit Diagram - arduino 4 channel voltmeter circuit diagram voltages are measured between points a b c or d and gnd or 0v remember to adjust the contrast pot so that the voltages on the lcd are made visible arduino voltmeter circuit diagram the lcd used in the circuit has the pin numbering shown in the lcd ponent information from the beginner s tutorial on this website it is important to check that the lcd that you are using has the same pin numbering as the circuit diagram making incorrect lcd connections can damage the lcd if you are using a lcd with different pin numbering use the arduino voltmeter circuit diagram circuit diagram for this arduino voltmeter is shown above connections connect high voltage side 220v of transformer to the mains supply and low voltage 12v to the voltage divider circuit connect 10k resistor in series with 4 7k resistor but make sure to take voltage as input across 4 7k resistor.

connect diode as shown connect capacitor and zener diode arduino uno has six analog input channels named a0 a1 a2 a3 a4 and a5 the voltage in the range of 0 to 5v applied to each of the pin can be converted into a digital value in the range 0 to 1023 using analogread function that means the sensitivity of each internal adc channel is 5 1023 which is equal to 4 88mv the program for digital voltmeter using arduino is shown below arduino voltmeter with lcd and 4 channels posted on may 27 2013 by starting electronics this arduino voltmeter measures four independent voltages make a mini arduino programmable 4 channel dc dvm this instructable will teach you how to use the arduino analog ports digital voltmeters dvms are a special case of analog to digital converters a dcs they measure voltage and are usually a function of a general purpose instrument called a software voltmeter circuit.

diagram the circuit uses a voltage divider on each channel to increase the readable range of the arduino analog inputs from 5v to about 50v for an explanation on how arduino measures voltage read the article on measuring dc voltage using arduino simple 0 to 5v digital voltmeter using arduino uno three digit led display 50mv sensitivity circuit diagram theory and program here is a useful simple and tested arduino voltmeter circuit which can safely measure input dc voltages from 0v to 30v including 12v it s easy to make a simple digital voltmeter using an arduino and 16x2 liquid crystal display lcd it s relatively simple to use an arduino to measure voltages the arduino has several analog input pins that connect to an analog to digital converter adc inside the arduino the arduino adc is a
