Yes, there is. It is called "Introduction to Microcontrollers" by Günther Gridling and Bettina Weiss from the Vienna University of Technology, written in 2007.

Unfortunately, it suffers from having a very generic name. It is short enough while going over concepts to take a person just beyond Arduino-land.

Is it possible to make an Arduino clone in a breadboard and then upgrade each component one by one?

It may be a nice escape route from Arduino to professional electronics.

Short answer: Yes. And you always could have.

Longer answer: It's been a while since I have thought about Arduino. But last I recall, it is just an Atmega chip connected to IO. Maybe newer ones have moved to ARM M0 or beyond. That's about when I stopped using Arduino.

But it isn't hard to just start from baremetal on those. You need the user manual for the actual chip so you can configure timers and such. Once you know how to set up one chip, you can set up most any chip.

I do think there is use for a plug and play system like Arduino. It is very user friendly to just use that IDE and get started on Arduino. My critique is that there is rarely a followup progression. That followup progression is critical.

Here's a video showing how to make your own "Arduino" [1]. All the hard work is done by the Atmega chip. So Arduino has built this mythos and this IDE that it seems you have to use. It traps people and prevents them from doing the exploration into the chip itself.

About the video: I expected more work. It's like 5 components and 5 wires. (Another video, suggested by the algorithm https://www.youtube.com/watch?v=sNIMCdVOHOM )

How hard is to change the programming language? I think in the video they use the Arduino programming IDE.

Ive always just used C. From my recollection, there’s an avr libc library. There’s tutorials online for how to do it. The big thing is once you have that progression path with knowledge like that book I linked, you have a lot of freedom.

Some chips can use Micro Python or even Rust. I have not explored those myself.
