Iam developing low cost ventilator for covid-19 panademic.iam using Heart pulse monitor in my basic model.Iam using Audrino uno with rlevent library codes.Can i use the library code for my YOU TUBE Presentation.Please acknowledge


You didn't say which library you're requesting permission to use, but the answer is almost certainly "yes".

Each library should contain a license that clearly defines the conditions for the use of the intellectual property. This will usually either be in a comment at the top of the source code files or in a text file named LICENSE or license.txt or LICENSE.md, or maybe in the readme file.

Copyright laws may differ from one jurisdiction to another, but in general if no license documentation is provided, then the IP is "all rights reserved". Even then, a "fair use" clause in the copyright law may allow it to be used in very specific cases, which could include discussing the source code in a video commentary. There is a lot of information on that subject easy to find online. Of course, you could not use such a library in an "open source ventilator". You could contact the library author, since it's possible they intend it to be open source, but just didn't bother to add a license. Since the Arduino world is based around open source priciples, it's likely this will not even be an issue.


     The library to be used is"Adafruit_SSD1306.h



The library to be used is"Adafruit_SSD1306.h

So, you should be asking Adafruit, not Arduino.

The clue is in the name.
Please don't PM technical questions - post them on the forum, then everyone benefits/suffers equally

Please don't bother Adafruit about this. They made the effort to clearly document the conditions under which you can use this library. You only need to know where to look.

Do this:
  • File > Examples > Adafruit SSD1306
  • Select any of the examples under that menu.
  • Sketch > Show sketch folder

This will open the subfolder of the library that contains the example sketch. If you then navigate up two folder levels you'll be in a folder that contains a file named license.txt. Open that file in a text editor and you'll see the license terms. This will almost certainly be a standard license (my guess is you'll see it's the BSD license, but I could be wrong), so you can find more information on what it means with a quick google session.

You might start here:


     Thank you.Sorry for disturbence


You're welcome. No need to apologize. I'm glad if I can be of assistance.

Best wishes for your project!
