CC50: Módulo 0 - Scratch

Introduction

Welcome to the tutorial for Scratch, a visual programming language designed to make coding accessible and fun for everyone. In this guide, we will walk you through the fundamental concepts of Scratch, helping you get started with creating your own interactive stories, games, and animations. This tutorial is based on the CC50 module provided by Harvard, and we're excited to help you harness the power of Scratch!

Step 1: Setting Up Scratch

• Access Scratch: Visit the Scratch website at scratch.mit.edu.
• Create an Account (optional):
  • Click on "Join Scratch" to create a free account.
  • Fill in the required information and follow the prompts to verify your email.
• Explore the Interface: Familiarize yourself with the Scratch interface, which includes:
  • Stage: Where your project is displayed.
  • Sprites: Characters or objects in your project.
  • Blocks Palette: The collection of coding blocks you will use.

Step 2: Creating Your First Project

• Start a New Project:
  • Click on "Create" in the top menu to open a new project.
• Add a Sprite:
  • Select a sprite from the library or upload your own.
  • Click on the sprite to see its properties and options.
• Set the Stage Background:
  • Click on the stage area and choose a background from the library or upload your own.

Step 3: Programming with Blocks

• Understanding Blocks:
  • Blocks are categorized into different types: Motion, Looks, Sound, Events, Control, and more.
• Adding Blocks to Your Sprite:
  • Drag blocks from the blocks palette to the scripting area.
  • Example: To make a sprite move, drag the "move 10 steps" block into the scripting area.
• Creating Simple Scripts:
  • Combine blocks to create sequences. For instance:
    1. Start with an "when green flag clicked" block.
    2. Attach a "move 10 steps" block underneath it.
    3. Click the green flag to see your sprite move!

Step 4: Enhancing Your Project

• Add Sound:
  • Select the sound category and drag a "play sound" block.
  • Choose a sound from the library or upload your own.
• Incorporate User Interaction:
  • Use the "when [key] pressed" block to allow keyboard control.
  • Experiment with different keys and actions to enhance interactivity.

Step 5: Saving and Sharing Your Work

• Save Your Project:
  • Click on "File" and then "Save now" to ensure your work is saved.
• Share Your Project:
  • If you have an account, click on "Share" to publish your project to the Scratch community.
  • Add a title and description to help others understand your creation.

Conclusion

In this tutorial, you learned how to set up Scratch, create your first project, program using blocks, enhance your project with sounds and interactions, and share your work with the community. As you continue to experiment with Scratch, consider exploring more complex projects and collaborating with others. Happy coding!
