DIY Arduino Nano Portable Oscilloscope

[@Everything-cb9sm]

Full wave form not display in oled display only half wave display

[@tyvek_]

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

[@adambeedle]

So cool 👏👏👏👏

[@HMProjects]

Thanks!

[@udayuday7768]

Viry nice video thanks

[@Mia_F22r_Trimarans]

beautiful project one question: does the new version 3 use the same sketch as version 2? Thank you

[@arvindh13]

Max voltage and Max current?

[@fixmyphone123]

Nice work sir

[@multimargejta123]

What is max voltage that it csn measure?

[@tylerpark9999]

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.

[@jaccca777]

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)

[@lokeshghodke9167]

What is the price of the project

[@edgarelectro4178]

Bravo

[@jumbo999614]

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?

[@ibrahimalfatih6059]

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.

[@sanjaygolani]

Hey can u give me the list of all components please

[@MrStingerjack]

This tiny thing can measure ac too?

[@EasyOne]

nice

[@HMProjects]

Thanks bro!

[@rodriguezmedinamarioalfons8638]

Does anyone know the bill of materials for this project?

[@neihsangapautu9096]

Can you measure 230VAC?

[@billnopoles1934]

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)).

[@smmojnu815]

please give me V3 code

[@lastmanstanding9389]

Nice, what size battery are you using? Is the source code the same for V2 and V3?

[@HMProjects]

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.

[@N.g.Chanal]

where is slap library?

[@HMProjects]

Any library you need you can install it from library manager.

[@ben2942bc]

I made a few of these , I sell to my friend at cost , is it okay?

[@rafiul1522]

Can i use 0.96" oled display??

[@HMProjects]

Yes, but make sure to use the right library.

[@МаратКайбышев-ф5к]

Hello. Good performance. Can I use OLED 0.96 SSD1306?

[@HMProjects]

Hello. I believe it will work but you have to use that library for the oled display that are you using.

[@cluetoeverything7492]

Hey bro which one should I download? There is another file named V3 What's the changes in that ?

[@HMProjects]

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.

[@bob-ny6kn]

I can do the same thing with the IDE Plotter: Serial.print(analogRead(A0));

[@yilmazebem]

There is insufficient explanation and insufficient information. How many volts can measure directly? Have you tried 220v?

Error compiling for board Arduino Nano

[@HMProjects]

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.
