Cipad_02. Cours d'Introduction à la Programmation Arduino, Leçon_02_Part 2 de 2.

Introduction

This tutorial provides a comprehensive guide to an introduction to Arduino programming, specifically focusing on the second lesson of the series presented by Daniel Talbot. The lesson utilizes the TinkerCad online simulator, allowing beginners to practice coding without the need for physical hardware. This guide will walk you through the key concepts and steps needed to successfully navigate the lesson.

Step 1: Set Up Your TinkerCad Account

• Visit TinkerCad.
• Click on "Join Now" to create a free account or log in if you already have one.
• Follow the prompts to complete your registration and verify your account if necessary.

Step 2: Access the Project for Lesson 2

• Use the link provided in the video description to access the specific project: Lesson 2 Project.
• Click on "Duplicate" to create your own copy of the project in your TinkerCad dashboard.
• Familiarize yourself with the TinkerCad interface, including the workspace and components available.

Step 3: Understand the Basics of Arduino Programming

• Recognize that Arduino uses a simplified version of C/C++ for its programming.
• Key components of an Arduino sketch (program):
  • setup(): This function runs once at the start and is used to initialize settings.
  • loop(): This function runs continuously after setup() and contains the main code.

Step 4: Implement Basic Code Structure

• Begin writing your Arduino code in the TinkerCad code editor. Here’s a simple code example to get started:

  void setup() {
    // Initialize digital pin LED_BUILTIN as an output.
    pinMode(LED_BUILTIN, OUTPUT);
  }
  
  void loop() {
    digitalWrite(LED_BUILTIN, HIGH); // Turn the LED on
    delay(1000);                      // Wait for a second
    digitalWrite(LED_BUILTIN, LOW);  // Turn the LED off
    delay(1000);                      // Wait for a second
  }
  

• This code will blink an LED connected to the built-in LED pin of the Arduino.

Step 5: Simulate Your Project

• Click on the "Start Simulation" button in TinkerCad to run your code.
• Observe the behavior of the components in the simulation.
• If the LED does not blink as expected, review your code for any errors.

Step 6: Modify and Experiment

• Try changing the delay times in your code to see how it affects the blinking speed:
  • Replace delay(1000); with delay(500); for a faster blink.
• Experiment with different components available in TinkerCad, such as sensors or additional LEDs.

Conclusion

By following these steps, you have set up your TinkerCad account, accessed the lesson project, learned the basics of Arduino programming, and successfully simulated a simple LED blinking project. Continue to explore TinkerCad's features and expand your skills by trying more complex projects. Engaging with community feedback can further enhance your learning experience. Happy coding!
