Variables in C programming language, which Arduino uses, have a property called scope. A scope is a region of the program and there are three places where variables can be declared. They are −Inside a function or a block, which is called local variables. In the definition of function ...
In addition to variables, every programming language also includes constants, which are simply variables that don’t change. They’re a useful way to label and change numbers that get used repeatedly within your program. For example, imagine you’re writing a program that runs a servo motor. ...

Unlike some other programming languages, Rust’s constants do not have a fixed memory location. Instead, they are functionally inlined wherever they are used, which can optimize performance. Static objects in Rust are akin to constants but with one significant distinction: they retain a single ...

Hi, need some help with converting variables into byte arrays for serial transmission on Arduino in each direction. I need to convert int, long, long long and float to byte arrays for transmission then back to those variables when received. I am new to C/C++ but not programming in general...
