@@Educ8s I want to make this voltmeter with common power source. I mean to say that, can the same battery be used for powering up the Arduino and measure the voltage level as well ? Please help me out
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.
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!
how I see it change the big voltage(input) to a small voltage(output), so there are some one that change from small to big? we talk about 1.5v input to 5v output
Question i have built this using a Arduino nano v3.0 the reading seems to be 2.66 volts out the arduino reads 15.1V the multi meter reads 12.44V is there something im doing wrong ?
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.
I've been trying to find a solution to this since I don't want to fry my UC if someone mistakenly puts the probes the other way around. I want it to be able to read both negative and positive voltage while keeping the resolution.
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
Put MAX471 next to this voltages meter circuit and you can measure current as well, form 0-3A. (+-6mA steps if you use 5v arduino and +-4mA steps if you use 3.3v arduino) Tutorial henrysbench.capnfatz.com/henrys-bench/arduino-current-measurements/arduino-max471-current-sensor-module-tutorial/ They are cheap on ebay. www.ebay.com/itm/3A-Range-Current-Sensor-Module-Professional-MAX471-Module-NEW-/201415109947?hash=item2ee546ad3b:g:iqEAAOSw3ydVrvZF Next step is Ohm meter, you can calculate that form voltage and current, but is not that accurate. Better use some good 0.1% resistor for that. Tutorial Ohm meter www.circuitbasics.com/arduino-ohm-meter/ Next step Capacitance Meter, her are some different circuits and sketches for that. www.circuitbasics.com/how-to-make-an-arduino-capacitance-meter/
change the values of resistor, so that the maximum voltage you intend to meassure, shouldnt create more than 5 volts on analog pin. this will also lower the resolution (the fine voltate you can meassure) . thats why the voltmeter has a voltage selection knob
Hi thank you for your movie. Pity i want to measure my 24 volt battery system than is 25 volt to little capacity. Direct voltage on the Arduino it seems me to risky, as one resistance burning day Arduino. Measure galvanic separated is better and more safer. If you know how I can Measure galvanic separated to a voltage of 50 or 100 volts DC let me know.
Hello Nick, How can I make this window "VOLTAGE" and "V". Can you help me understand? I wanted to learn how to draw these windows to other units and sensors. Thank you.
Hello friend, the Voltage window is just a .bmp file I designed in Photoshop. Check out this video in order to see how to design your own window and how to load it to an Arduino sketch: ruclips.net/video/aUZP0nzxc0k/видео.html
Why not learn people how you can make those "volt sensor" themselves for almost noting? Or are the hobbyist that lazy now a day that they don't want to put two resistors on a breadboard?
so basically its a 2 resistor voltage divider which takes 0-25v and divides it to 0-5v?
Yes! That's exactly what it is!

HI Nick,
Can't we use the direct output of a battery on to A0 pin if the battery voltage is below 5v?
To make the volt meter read higher voltages you could use a switch to switch another resistor into the voltage divider. Just a thought.
Your Channel is fantastic! Thanks for all!
Thank you very much Renato!

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

Very nice.
I have a project in mind:
build Amermeter or checking the capacity of the battery.
thanks
this is a verry usefull project, however.. i need to mesure around 220v. Wich sensor is capable of doing this??

hello, can you write a code for 4 voltage sensors at once with the ability to write to sd and display on the screen?
Hi. The value always change, is it normal?
Why's that?
Thank you so much
Marc.
Excellent Nick - many thanks my friend. Lee
Can you give me the Correct Coding of this Voltage Sensor Project? I got Some while compilation.
Love your videos, very educational, Any chance of doing a video with 5110 and an INA219? Keep up the good work
its possible as well with
Arduino PRO MINI 3,3V 8Mhz - ATmega328 ?
I measured a 1.5v battery and got 2.8v reading on serial monitor.
What could be the problem?
how I see it change the big voltage(input) to a small voltage(output), so there are some one that change from small to big? we talk about 1.5v input to 5v output
Waked Industrial Ltd. search on ebay for "Boost converter"
Thanks Nick!
I learn alot from your videos. :)

Check the resistor values. The more accurate the resistor value you enter in the code, the more accurate results you are going to have.
can you build project with STC15L204 + NRF24L01.
wireless sensor.
I could not find anywhere on the network
thanks.

Hello, how do I read negative voltages on the display, because I want to make a symmetrical source.
I haven't tried that so far so I can't help you right now..

How to make this 2 in 1? Clock and voltmeter in 1 display?
wow, your channel is so amazing^_^
.note: if you draw the circuit before to do the work that's will be great
Nice project!
Maby a DIY Multimeter project?

you said that up to 25 v we can calculate with this. Then how to calculate beyond this (like 45v to 52v) in a battery
change the values of resistor, so that the maximum voltage you intend to meassure, shouldnt create more than 5 volts on analog pin. this will also lower the resolution (the fine voltate you can meassure) . thats why the voltmeter has a voltage selection knob
The link to the voltage sensor board is dead. It states that the site can't be reached.
Working fine now for me.
On my PC I have to delete the URL portion before gearbest.com then it works. It redirects fine on my phone. Stoopid conprooter.
how can I make it show atleast three decimal places?
can we measure the ac voltage....?
Hello Question what values are them resistors?
Check the video carefully, the resistor values are shown in the video
+educ8s.tv I just saw it thank you somehow I missed it.
hi Nick,
i copied your code and i have the following error message
exit status 1
'readVoltage' was not declared in this scope
Thanks for your time!
hi again, i fixed it , i had to comment it...
Thank you!

How ı can read higer voltage
Can you send me the circuit daigram of this project
How about a GPS speedometer,please? :)
That can show your current speed in km/h or mph.
Yes, that's a good idea. I will try to make a project like this!
+educ8s.tv Thanks!
That is awesome! :)
My 5110 is half as responsive and clear as yours...Why?
HOW MANY VOLT IT CAN MEASURE
This sensor can measure up to 25V DC.
Good.

keep getting errors wont upload the code or bitmaps
looks expensive for 2 resistors ????
Ray Bright Its the Arduino which is so "expensive"
Sir plz share the code
Y u need this sensor?! Just use simple voltage divider
Of course, for accuracy. To build our potential divider, we have to select precise resistors to get 5V against 25V.
Why not learn people how you can make those "volt sensor" themselves for almost noting? Or are the hobbyist that lazy now a day that they don't want to put two resistors on a breadboard?
Sir, your code is not working and it's not funny HAHAHA
Are you greek?
