You need to translate one range of values to another. I write in python. Arduino scripts have a function like map, I wonder i ... value) from the current range of values (fromLow .. fromHigh) to the new range (toLow .. toHigh) specified by the parameters.

Everywhere it is written the standard SI, SO, SCL, and so on, and here it is not clear, with what information I did not find

I did a project where the raspberry controlled the arduino via usb, and the arduino, in turn, receiving data through com port ... avoid burning out of ports(from malinai or separately). How can we avoid burning them out(without using galvanic isolation)?

There is an Arduino Nano board with, most likely, a burned-out programmer. Can I upload sketches without it?

I decided to find out what the code for arduino is written on, Google says that in C\C++. But I don't understand which one? Or maybe both?

I'm moving from arduino to stm32, there was a problem with the UART'om, or rather with understanding how to do it "beautifull ... buffer to create. Plus three more UART communication options, which one is better suited for emulating Arduino Serial.read()

I have a BMP280 barometer (HW-611). I connected it in different ways. I used the Adafruit library for BMP280, ran the bmp280test example, but writes "check wiring". How to connect it, which library to take?
