Raspberry Pi For Beginners - 2022 Complete Course - Activity 06 - Change the Powered-On LED When Pressing the Button

The video tutorial guides viewers through a project involving a circuit with multiple LEDs controlled by a push button. Initially, all LEDs are off. Pressing the button cycles through turning each LED on while others remain off. The tutorial emphasizes detecting button state changes to trigger LED toggling, requiring the use of a variable to store the previous button state. Viewers are encouraged to practice the concepts before proceeding to the solution.

What is the importance of toggling the LEDs only when the button state changes?

How can you keep track of the button's previous state?
