What is the best environment to start developing a program for Arduino?

Question

Arduino

Good afternoon! The desire was born to make a project based on Arduino. Bottom line: Several sensors are connected to the Arduino, transmitting data to the com port. I want to implement a program on a PC that will take data from the com port, interpret them, including into three-dimensional graphs. I plan to later port the program to Raspberry to get a highly specialized mobile PC. Tell me what is the best way to write this program and the interface to it? In what language, in what environment? If possible, in more detail, as for fools)

Answer 1

C# on a computer arduino studio for arduie, communication via com port. And you will reach the raspberry there and you will choose. With what is good that it is easily tolerated

Answer 2

I plan to later port the program to Raspberry

It is clear that in SI. I don’t know if there is JAVA or Python on Raspberry (maybe), but C# is definitely not there.
In reality, for a PC, write on what you know how well, and it will be seen there

Answer 3

100% Arduino IDE - C, C++ language.
This is a simple start, you can say from the spot. Flashing an LED is the dream of any programmer.
And then you need to look for something more "Fashionable". There are many options.
At the top of the pyramid of possibilities Microchip Studio - Language C, C++, Assembler.
