This is my all in one DIY Arduino project. This device has multiple modes and it can track analog readings from sensors or components, measure resistance and drop voltage of the diode. It has built in continuity test, temperature sensor. It can show voltage of the battery and also produce signals using PWM.
In this project I used Arduino nano, 128x32 led display, couple of resistors and push buttons, temperature sensor and a buzzer for continuity test.
It uses internal 1.1V voltage reference so reading is much more precise.
It was fun project, and it can be improved more.
I hope you will like my video and sorry for my bad english.
One of the most useful part of a continuity tester is the ability to look at forward voltage drop on the diodes, transistors etc, a very useful feature for repairs to power supplies when looking for shorted components.
You should post a video on " how to make a digital multimeter "
you can check new and better version here ruclips.net/video/vuz9x18RQl0/видео.html
this project is very handy for an elctronic beginner. very well made and explained, it looks good too for those icons in the display. Genius!
Dude this is super. You need to take a video showing how this multimeter is made. It would be great if you could share your codes. Because I have to present it to my professor as a university dissertation. Do you understand me?
www.instructables.com/id/Arduino-Multimeter-and-Components-Tester/
You should only present this as work if you fully understand it, don't forget your references.
Is the arduino code and schematic available?
Nice Project, what is the maximum value of track resistance in ohms upto which the buzzer will beep ?
It should be less than 5 ohm I do no know what is yours ?
Re the description
What is the point of buying the screen if people do not have the sketch or schematic ?
Add capacitance, inductance, current,& frequency
Nice job - really useful Nano DMM project!
where could i download the code? good video!
This is the sketch arduino for this project I used Arduino nano, 128x32 led display, couple of resistors and push buttons, temperature sensor and a buzzer for continuity test?
How can you get the project to use at the university?
can not you publish the schematic and code of this project?
Great... Only missing is Capacitance measure...
good video, what capacity does it have in your measurement of components?, minimum and maximum measurements of components, thanks
Good job, I was looking a arduino with voltage drop with diode.
Link is not working properly.. error please update
Some Idea how to merge Diode test and continuity test in one? Like if Dv=0 or Dv=0.0001 may infer an impedance less than 50ohm calling the speaker.
What library did you used for the OLED?
U8glib and U8glib2 are the best libraries for oled graphics and animations. Those libraries support almost all type of displays. But I had problems with the I2C communication when connecting other modules that use I2C and this is a problem from the library itself. Best of luck in your projects ❤
@@ibrahim.t3530 Thank you! ❤️
Hello, I could ask you for a program and schematic for this component tester? Thank you.
We can make it by LCD 16×2
What is the different
Nice project!
It is very helpful for our oroject. however we were thinking of adding electronic component (i.e. IC, Diode and transistor). Is it possible to make it as only one tester (combined IC, diode and transistor tester)?
Can you help us sir? thanks
Is this highly accurate?
Nice video but the link in the description doesn't work.
I am currently making this - if there was an option to add RJ45 Lan tester into this I would be so happy :)
Wow its more useful than regular meter
i am glad you like it, hope you saw new and better version ruclips.net/video/vuz9x18RQl0/видео.html
Do you have a circuit sir?
Are all those functions part of the same sketch I wonder. Not knocking it though, good work and an interesting project as a whole.
Why wouldn't all the FUNCTIONS be part of the same sketch ?
You can only load 1 sketch at a time
although this project has so much more potential on ESP32
great and inspiring work !
Awsome project i like it thumbs up buddy
thank you :)
i do some change to the code and fixed for arduino pro mini to be smaller. at first time it work. at secont time after about 3-4 months i try to get one more with againe arduin pro mini (not same factory) but is to slow, he "lag" about 1,5 sec to change menu or to measure ohm, diode, continuity test. the sketch is 87% i try to work on uno but the same lag. can you have same problem? and how to fix?
can you send me your code at arduino.b2016@gmail.com
@@VolosProjects done , i send you the code!! xD
@@VolosProjects do you find solution for my problem? i try more but nothing the same lag
:(
Crazy invention bro...I like it
Nice project. I like it!
I found your project on instructables.com and the sketch you uploaded there is not working. the compiler says, that a few things are not declared (like sensor.begin)
whic arduino IDE you are using, did you install al libraries?
@@VolosProjects I installed every library, that is needed the gfx library and ssd1306. my ide version (windows) is 1.8.5
try with this libraies it-edukacija.eu.hr/multidruino/librariesMulti.zip
and also try this sketch it-edukacija.eu.hr/multidruino/multiMultimeter.zip
@@VolosProjects the ide says, that the zip contains no library🤷♂️
How to connect small lipo cells? With charger module?
Very inspiring video You did a great job My congrats, what heartbeat sensor did you use here ? I am (just like all other subscribers I think) interested in the hardware and software details.
It's a nice and usefull ARDUINO NANO project !!!!!
Again, you did a great job - nice work - keep on this track.
tnx my friend . it is cheap pulse sensor from ebay . www.ebay.com/itm/Pulse-sensor-Heart-Rate-Sensor-PulseSensor-for-Arduino-Raspberry-pi/272382782218?hash=item3f6b476b0a:g:SEAAAOSwOyJX366-
This is amazing how do we make it bro your a legend ❤❤❤❤❤❤❤ pls 😂
((multifunctionArduino.ino:6:34: fatal error: Fonts/FreeSans12pt7b.h: No such file or directory))
I'm still a beginner and do not know where I have to insert the file, maybe someone can help me here?
You need to create a folder called "Fonts" inside your sketch folder. copy the .h files in question into that folder
Can you share schematic and code please
how can you wissle and speak at the same time???
i recorded audio later, my english is not at that lavel, to record and talk at the same time.
@@VolosProjects can you share the scetch?
Will you sell on line
@ 4:43 Baterry typo - Battery - Cool Combinations
It can measure transistor, thyristors and triacs?
no, only, resistance and voltage drop, but you can upgrade it for tranzistors.
Volos Rakic Ok Thanks
this is quiet interesting....can u please share the circuit and all other details ?
i will try , give me a moment

Thx for sharing this amazing project.
You should add a gas sensor
Can you please Shair circuit diagram and code?
code provided not working showing error less memory
code kaise milega
Much for this project sir
first of all great work and nice one :D but i have one problem i download the Adafruit_GFX.h>
Adafruit_SSD1306.h, OneWire.h, DallasTemperature.h and if i press config he has error "sensors" why do that? can you help me to fix this? thanks
i dont understend, you press config?
did you download aned install whole libraries or juts ".h" files?
i install whole libries with zip. on arduino ide you have and the "upload" and the "config" button.
the error is this. "C:\Users\my pc\Downloads\multifunctionArduino\multifunctionArduino.ino: In function 'void setup()':
multifunctionArduino:179: error: 'sensors' was not declared in this scope
sensors.begin();
exit status 1
'sensors' was not declared in this scope.
i forgot to tell you i dont use the 128x32 led display i try with 0,96" oled like your "upgrade multi-druino"
p.s
sorry for my english :(
sensors.begin is function realted with temperature sensor. I dont know why it is not working ,try this sketch , it is made for upgraded version it-edukacija.eu.hr/multidruino/multiMultimeter.zip
nothing againe with this code has problem with DS3231 and i try to fix with no result and i dont know why does this problem.
Great proyect!!!
thank you :)

Excelent Project!! @Volos Projects but i have a problem imgetting this error "class Adafruit_SSD1306' has no member named 'setFont" what is it wrong?
Thanks
Sir Diagram of this project
Very very nice!
Please make video about how to make It.
Edit: Ok i saw tutorial on instructables
where is the tutorial?
like it dude
tnx man
most welcome
Exelent!
Plz make a tutorial video
Are you still selling it? Can I please have one?
give me you mail, please.
You can send me an email at rashed1228atgmaildotcom
Good job its amazing, i have a question is there any limit in resistance meter? or range for measuring resistance?
yes, it is most accuate in range from 0-10K , it can be used for resistors upo to 50 K but is not to accurate, but it is enough to identify resistor,
Awesome!
Please code and schematic
Sir diagram pls
Can i have the schematic n code

Dale Smith thanks
Your project is very good, please can you help me this month to do a project and I liked your project can you give me the code.
The code in which I made errors in Arduino, I am interested and thank you.
can you explain your project?
multimeter that tests resistances, capacitances, inductances and continuity. Thanks for your reply to my message
i know only how to measure resistance and continuity, i think that measuring inductance is not possible. capitance is maybe possible with additional modules. i am not sure
Can you send me a millimeter that measures resistance and continuity, I will not forget you.
I am a novice student in electronic
I want to learn from you and wish you more success and success.
