The Arduino programming language is based on C++. In Python, we use indentation to identify the body of an if statement, while statement, a function, or a class. An Arduino sketch will use {} instead of indentation.
While the {} are required syntax, almost all Arduino code that we'll see will be nicely indented as if it was Python.
Similarly, Arduino statements are separated by ; (semicolon). Python statements end at the end of the line, or the end of the matching (), [], or {}. It's challenging—at first—to remember the ; (semicolon). When we try to upload the sketch to our Arduino, the final syntax check will alert us to missing ;(semicolon).
Arduino has two kinds of comments: everything after // is a comment. This is similar to Python's # comment delimiter. Also, Arduino programs can have longer comments which begin with /* and end with */. This will often be used similarly to Python's ''' triple-quote strings. The Arduino /* */ comments can be used...
