DIY Arduino Nano Portable Oscilloscope
HTML-код
- Опубликовано: 4 окт 2024
- I made myself an portable oscilloscope based on arduino nano, it can measure all kinds of wave forms up to 25 Khz and also can see on display the frequency and duty cycle. You can change the volts per divizion and time base. I will put a link to schematic, pcb and arduino code.

Thanks for watching!!

For what reason, when you turn on this device that is not connected to a signal source, it shows 53.4 v and there is simply no graph
So cool 👏👏👏👏
Thanks!
Full wave form not display in oled display only half wave display
Viry nice video thanks
Nice work sir
nice
Thanks bro!
Bravo
hi, thanks for sharing. how would I go about obtaining an audio signal out of this so It can be a part of my signal chain? sorry real new to this hobby. Have many DIY plans of this nature, so the information shared online is always appreciated.
beautiful project
one question: does the new version 3 use the same sketch as version 2?
Thank you
Hi! Nice Project! can i ask you about how you can read up to 25kHz signal frequency? Because i only can read only up to 3kHz using while and millis. Thanks for sharing.
I can do the same thing with the IDE Plotter:
Serial.print(analogRead(A0));
I'm just beginner. Can it measure in any voltage?
I learned that Arduino pin is 5v. Anything more than 5v will destroy Arduino.
So I don't understand incoming signal.
what is a50v on the left of the screen and av... on the right of the screen?
Hi! Thanks for sharing the schematics, and source. Is it possible to increase sampling rate if I decrease the resolution? I'd like to measure digital signal, (only present or not, eg. check a car audio front panel)
Max voltage and Max current?
Hey can u give me the list of all components please
Does anyone know the bill of materials for this project?
There is insufficient explanation and insufficient information. How many volts can measure directly? Have you tried 220v?
What is the price of the project
Nice, what size battery are you using? Is the source code the same for V2 and V3?
Thanks, the code is the same for both versions, only the pcb is different and the battery is 1x3cm/ 170mAh, is a bit too small for this project but it was the only battery in small size that I had at that time.
What is max voltage that it csn measure?
I made a few of these , I sell to my friend at cost , is it okay?
This tiny thing can measure ac too?
Can you measure 230VAC?
yes! But, please use a voltage divider on input since Arduino is operating with 5V. - and take care of the leathal voltage. To see AC you have to raise the zero level, to around 310V at the entrance - or after the divider to 2.5VDC (it seems it is done already with D12 and R2). Remember 230VAC is around 620VPP (230 * sqr(2)).
Hello. Good performance. Can I use OLED 0.96 SSD1306?
Hello. I believe it will work but you have to use that library for the oled display that are you using.
where is slap library?
Any library you need you can install it from library manager.
Hey bro which one should I download? There is another file named V3
What's the changes in that ?
Hi. The difference between V2 and V3 are mostly in pcb design, in this video I used the version 3 so you should download V3. I put there V2 files just in case someone wants to make that version but probably I should delete it not to be any confusion.
Error compiling for board Arduino Nano
In Arduino IDE go to Tools/Board, select Board/Arduino Nano and on Processor try ATmega328P or ATmega328P ( Old Bootloader ) if still have the same error try different ports or it may be the IDE itself.
Can i use 0.96" oled display??
Yes, but make sure to use the right library.
