Variable Scope and fixing error: '_______' was not declared in this scope?

The video tutorial explains the concept of variable scope in programming, focusing on local and global scopes. It uses examples in the Arduino IDE to demonstrate how variables are confined within curly braces, affecting their accessibility across different functions. The tutorial also highlights the importance of minimizing global variable use to avoid complex bugs, providing practical advice on managing variable scope effectively.
