Organise large Arduino codebase with libraries, files and folders // Arduino CLI, Nano 33 BLE Sense
5,544
Published 2021-01-15
I used to have long Arduino *.ino sketch files that were difficult to debug and add features. In this video, I share several incremental steps to take to split a big Arduino code file into separate different files and folders for future maintainability. Plus, we will use Arduino CLI to install libraries and track its version. We will use the Arduino Nano 33 BLE Sense board for a practical example in one file before splitting the code into manageable bits.

Yes millis are awesome until i find library called taskschduler .

Thank you so much for the step-by-step approach, while still keeping the discussion at a high enough level that we don't get bogged down in the details. It takes a lot of skill to develop tutorials to this level. I've learned so much from you!
-
Excellent... Txs .This should be taught very early on as file management is a big problem...for me !
-
Wow! I can say I have never found a video in which everything is explained the way you did. Crisp, Clear and thorough.
-
Thank you! Your teaching style is so nice - clear, concise, moving quickly from point to point but not skipping over any valuable notes.
-
Yeah, I’ll keep rewatching this 😊; I love it ❤
-
Such an excellent video. 20 very lightweight and life changer minutes. Loved it.
-
Really love your videos and your straightforward approach to explaining things. Thank you Sayanee 🙂
-
You have done a great job in creating a video like this. I work in the learning organization of a large company and I know how much effort it takes to create good training material. Here I have to say it is perfect. Great content, well structured, easy to understand and you are a great instructor and it's a pleasure to listen to you. I'll definitely check out the other videos from you.

Really well explained. Great video.
-
Thank you so much for creating this video
-
Extremely helpful

Thank you @Sayanee, keep the excellent work going! Found your video thanks to google's recommendation. I loved your evolutionary approach to maintaining a readable and reusable code base — I see its value in small and large complex projects. I also wanted to salute your overall train of thought, I watched your PCB manufacturing and debugging videos. These concepts can be applied to problem solving projects and shorten the path to an MVP that sells the product. This is what I call quality content. Thank you.

Really really good video. Thank you so much.
-
Thanks! It was very useful video for me :)
-
Thank you, it is a really helpful video!
-
i appreciate your effort to give us the timestamp and resources link! Thank you so much👍 .. and just my thought that PlatformIO would simplify all of these steps i guess? EDIT: Especially to manage multiple source files and/or libraries.

At 3:02, I saw that your vscode editor had shown red underline, how can you fix it?
