What can be implemented on Arduino?

Question

Arduino

I would like to know if you take Arduino NANO or Arduino UNO, then what programs can be written on them, am I talking about the scale?

Answer 1

You have 32-0.5kb per code, 2kb of RAM and 1kb of non-volatile memory.
It's hard to say how much code you will fit, it all depends on what and how you will write the program.
You can abandon the bootloader and wiring programming and switch to pure C with Keil code development, for example. It will be more correct. True, an external programmer is required, but this is not a problem - you can assemble it, you can buy it.

Answer 2

Everything is the same that is done in the form of "hard" electronic circuits, but programmable and disassembled-reassembled.
You can even build CNC and process control systems, although Siemens is probably better in this area.

Answer 3

For example, turn on the light in the toilet in case of poor lighting and a change in the rangefinder reading and be proud of it.
