This is where you set things up that have to be done once before the loop starts running, and then don’t need to happen again.
This contains the main code of your sketch. It contains a set of instructions that get repeated over and over until the board is switched off.
Arduino includes a number of symbols to delineate lines of code, comments, and blocks of code.
- ; (semicolon)
Every instruction (line of code) is terminated by a semicolon. This syntax ...
