- Welcome to Our Channel REES52
In this tutorial, we are making a Digital Voltmeter using a 16*2 LCD Display with Arduino Uno. 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 ten-bit converter, meaning that the output value will range from 0 to 1023. We will obtain this value by using the analogRead() function. This project will show you the values up to 5v.
If you know the reference voltage--in this case we will use 5 V--you can easily calculate the voltage present at the analog input. To display the measured voltage, we will use a liquid crystal display (LCD) that has two lines of 16 characters.

what was from the two tools reading is true multimeter or volt meter ?
Hi can you briefly describe the way of simulating the code and about the software..
thanq
can you share the simulation of the circuit on proteus
nothing is showing up on my lcd just lines
how to make the limit of measure is more than 5 volts or infinity .
upto how much voltage it measures?
