CIPAD 34: Première leçon d'initiation aux Micro Servo Moteur.

Introduction

This tutorial serves as an introduction to micro servo motors, aimed at beginners in Arduino programming. It will guide you through the basics of how micro servo motors work, their applications, and how to set up your first project using these components.

Step 1: Understanding Micro Servo Motors

• Definition: A micro servo motor is a small, lightweight motor that allows for precise control of angular position.
• Applications: These motors are commonly used in robotics, RC vehicles, and other automated devices where precise movement is required.
• Components: Familiarize yourself with the main parts of a micro servo:
  • Motor
  • Gear train
  • Control board

Step 2: Gathering Materials

To get started, you’ll need the following components:

• Micro servo motor
• Arduino board (e.g., Arduino Uno)
• Jumper wires
• Breadboard (optional for organization)
• Power source (e.g., battery or USB)

Step 3: Wiring the Micro Servo

1. Connect the Servo:

   • Control Wire: Connect the control wire (usually yellow or white) of the servo to a digital pin on the Arduino (e.g., pin 9).
   • Power Wire: Connect the power wire (usually red) to the 5V pin on the Arduino.
   • Ground Wire: Connect the ground wire (usually brown or black) to a GND pin on the Arduino.

2. Diagram Reference: Use the Tinkercad links provided for visual representation of the wiring:

Step 4: Writing the Arduino Code

To control the servo motor, you’ll need to upload a simple code snippet to your Arduino. Here’s a basic example to get you started:

#include <Servo.h>

Servo myServo;  // Create a servo object

void setup() {
  myServo.attach(9);  // Attach the servo on pin 9
}

void loop() {
  myServo.write(0);   // Move to 0 degrees
  delay(1000);        // Wait for a second
  myServo.write(90);  // Move to 90 degrees
  delay(1000);        // Wait for a second
  myServo.write(180); // Move to 180 degrees
  delay(1000);        // Wait for a second
}

• Explanation: This code initializes the servo and rotates it to three different positions (0°, 90°, and 180°) with a one-second delay between each position.

Step 5: Testing Your Setup

• Upload the Code: Connect your Arduino to your computer and upload the code using the Arduino IDE.
• Observe the Servo Movement: After uploading, observe the servo motor as it moves to the preset angles.
• Troubleshooting: If the servo does not respond:
  • Check your wiring connections.
  • Ensure the power supply is adequate.

Step 6: Exploring Advanced Projects
