Hi there! Let's learn about how pressing a button can play two different tunes. Imagine you have a button that can play music:
First Press: When you press the button once, it plays the first tune. It's like saying, 'Play the first song!'
Second Press: When you press the button one more time, it stops the first tune and starts playing the second tune. It's like saying, 'Now play the second song!'
So, each time you press the button, it changes the music from one tune to the other. Press once – hear the first tune. Press again – hear the second tune! Pretty cool, right?
