Visible and Non-visible Components in MIT App Inventor :emoji:

:dart: What We'll Learn Today

Welcome, young app developers! Today we're going to discover the two amazing types of components in MIT App Inventor:

• Visible Components - Things you can see! :emoji:️
• Non-visible Components - Hidden helpers that do cool stuff! :emoji:‍:emoji:️

:bulb: Did you know?

Just like a magic show has things you can see on stage AND helpers working behind the curtain, apps have visible and non-visible parts too! :emoji:

Watch and Learn! :emoji:

Let's Get Started! :rocket:

The Two Types of Components in MIT App Inventor

There are two main types of components in MIT App Inventor: Visible and Non-visible. Let's explore what makes each one special!

One. Visible Components - The Stars of the Show! ⭐

Visible components are the parts of your app that users can actually see and touch on their screen. They're like the actors on a stage!

Examples of Visible Components:

• Buttons :emoji: - Users can tap them!
• Labels :memo: - Show text on the screen
• Images :emoji:️ - Display pictures
• TextBoxes ⌨️ - Where users can type

:information_source: Remember! If you can see it on your phone screen when using an app, it's a visible component! These are the parts that make up the User Interface (UI).

2. Non-visible Components - The Secret Helpers! :emoji:

Non-visible components are the behind-the-scenes heroes! Users can't see them, but they make your app do amazing things by using the special features of the phone.

Examples of Non-visible Components:

• Text-To-Speech :emoji:️ - Makes your app talk!
• Sound :emoji: - Plays music and sound effects
• Clock :alarm_clock: - Helps with timing
• Camera :emoji: - Takes pictures (the camera component itself is invisible, even though the pictures are visible!)

:bulb: Fun Fact!

Non-visible components are like the engine in a car - you can't see it while driving, but it makes everything work! :emoji:

Quick Check! :white_check_mark:

Let's make sure we understand:

• Can you SEE it on the screen? -> It's a Visible Component
• Does it work behind the scenes? -> It's a Non-visible Component

You Did It! :star2:

Congratulations! You now know the difference between visible and non-visible components in MIT App Inventor!

You're becoming a real app developer! Next time you use any app on a phone, try to spot which parts are visible components and think about what non-visible components might be working behind the scenes. Keep up the amazing work! :tada:
