Arduino Project: DIY Voltmeter using a simple voltage sensor and Arduino Uno and a Nokia 5110 LCD.

In this video we are going to learn how to build our own voltmeter using a very inexpensive sensor. The voltage we measure is then displayed in a Nokia 5110 LCD display. This project is very easy to build and great learning experience.

Want to learn to code?

Your Channel is fantastic! Thanks for all!

Love your videos, very educational, Any chance of doing a video with 5110 and an INA219? Keep up the good work

[KenHeinrich]

To make the volt meter read higher voltages you could use a switch to switch another resistor into the voltage divider. Just a thought.

Well, this is a good video to learn the essential elements of circuitry or code, but standard LED voltage/current meters are better suited price/compactness-wise in real projects. Thumbed up.

HI Nick,

Can't we use the direct output of a battery on to A0 pin if the battery voltage is below 5v?

Having a similar issue, I've been using this video as a guide for a college project but I get the same error Exit status 1
Error compiling for board arduino /genuino uno which other people are having. I know it's probably to do with me needing the right libraries (I downloaded the Nokia 5110 library from the previous video) however this alone didn't work, could you please let me know what else you needed for this to work? I noticed that a lot of people who do these tutorials forget what libraries they downloaded and forget to mention them.
It would be a great help!

Hello again I'm back :) I did work out the resistor Voltage dividing But I need to go a step beyond 25v. I need to monitor some batteries from 2v up to 70v DC. What type of resistors would i need for that? Sorry not good at voltage dividing resistors.

[KnaufL]

so basically its a 2 resistor voltage divider which takes 0-25v and divides it to 0-5v?

wow, your channel is so amazing^_^

.note: if you draw the circuit before to do the work that's will be great

[tomshalom]

Very nice.
I have a project in mind:
build Amermeter or checking the capacity of the battery.
thanks

[leehewitt]

Excellent Nick - many thanks my friend. Lee

[joacimwennerberg]

Thanks Nick!
I learn alot from your videos. :)

is it possible to drive more than one 5110 display the same time with an arduino uno?

[bertpeeters]

this is a verry usefull project, however.. i need to mesure around 220v. Wich sensor is capable of doing this??

[lyrafiel]

Hey there ! As you said it can measure upto 25V DC. What about measuring AC voltages ? Could this sensor be used for that ?
I want to track AC voltage across a solar inverter output and then display the power output I am getting across it.
So please suggest something to measure upto 230V AC using arduino and sensor.
Thanks!

[KaienSanderOfficial]

Nice project!
Maby a DIY Multimeter project?

[MPElectronique]

Hi. The value always change, is it normal?
Why's that?

Thank you so much
Marc.

[nikolaig]

hello, can you write a code for 4 voltage sensors at once with the ability to write to sd and display on the screen?

[abdurrehman]

your code is not stable on ardino why?? everytime its need to upload on ardiuno. and display disappear after some moments why?? please answer as soon as possible

[vittoriovizzaccaro]

its possible as well with
Arduino PRO MINI 3, 3V 8Mhz - ATmega328 ?
