Let's look at loops in Arduino. Specifically, we look at "while," "do while," and "for" loops and how to apply them in our programs. In essence, loops allow us to execute chunks of code repeatedly without needing to copy and paste. They also change the flow of the program, and we can change the way loops execute by modifying their conditions as well as using the "break" and "continue" statements.
