3 Apps en AppInventor - Sistemas Embebidos

Summary

The video showcases an educational session on creating event-driven applications using App Inventor, a user-friendly platform developed by Google for Android app development. Three applications are highlighted: a cat sound app that vibrates and makes noise when the image is pressed, a drawing app that allows users to create art on a canvas, and an Arduino-controlled car app that uses Bluetooth for remote commands. The session emphasizes fundamental programming concepts and encourages creativity, illustrating how simple applications can pave the way for more complex projects in the future.

Takeaways

• 😀 App Inventor is a graphical programming environment created by Google for building Android applications.
• 🎨 The simplicity of applications made with App Inventor allows for covering basic needs on mobile devices.

Q & A

What is the purpose of the practices mentioned in the transcript?

The purpose is to learn how to program event-driven applications using App Inventor.

What is App Inventor?

App Inventor is a graphical programming environment created by Google for developing applications intended for the Android operating system.

What limitations do applications created with App Inventor have?

The applications are limited by their simplicity, but they can cover a wide range of basic needs on mobile devices.

Describe the first application presented in the transcript.

The first application shows an image of a cat that, when pressed, emits a meow sound and causes the phone to vibrate.

What additional feature does the first application include?

It includes an accelerometer that detects movement, triggering the sound and vibration when the phone is shaken.

What functionality does the second application provide?

The second application acts like a paint program where users can draw on the screen and manipulate the image using buttons.

How can users modify their drawing in the second application?

Users can change the brush color, increase or decrease the brush size, and clear the canvas.

What is the main purpose of the third application?

The third application controls a cart programmed with Arduino and uses buttons to send commands via Bluetooth.

How does the third application send commands to the Arduino?

Commands are sent through Bluetooth using a sequence of integers that correspond to specific actions for the cart.

What were the main learning outcomes from developing these applications?

The main outcomes include understanding simple programming concepts, the functionality of various elements, and the importance of structuring code blocks effectively.
