FABRIQUER UN SONAR A ULTRASON ! [arduino]

Introduction

In this tutorial, you'll learn how to create a simple ultrasonic sonar system using an Arduino Uno, an ultrasonic sensor, and a servo motor. This project is not only a great introduction to electronics and coding but also demonstrates practical applications of sonar technology.

Step 1: Gather Your Materials

Before you start, ensure you have the following components:

• Arduino Uno
• Ultrasonic Sensor
• Servo Motor
• Jumper Cables
• USB Cable for Arduino connection

You can find links for purchasing the components in the video description.

Step 2: Set Up the Arduino IDE

1. Download the Arduino IDE:

   • Visit Arduino Software to download and install the IDE on your computer.

2. Install Required Libraries:

   • Open the Arduino IDE and ensure that you have the necessary libraries for the ultrasonic sensor and servo motor.

Step 3: Wiring the Components

Connect the components using jumper cables as follows:

1. Ultrasonic Sensor:

   • VCC to 5V on Arduino
   • GND to GND on Arduino
   • Trigger pin to digital pin 9 on Arduino
   • Echo pin to digital pin 10 on Arduino

2. Servo Motor:

   • Connect the power wire (usually red) to the 5V on Arduino
   • Connect the ground wire (usually black or brown) to GND on Arduino
   • Connect the control wire (usually yellow or white) to digital pin 11 on Arduino

Step 4: Upload the Arduino Code

1. Access the Code:

   • Copy the code provided in the video or access it directly from Pastebin.

2. Paste the Code in the IDE:

   • Open the Arduino IDE and paste the copied code into a new sketch.

3. Select the Correct COM Port:

   • In the IDE, go to Tools > Port and select the COM port corresponding to your Arduino.

4. Upload the Code:

   • Click the upload button (right arrow icon) to upload the code to your Arduino.

Step 5: Set Up Processing Software

1. Download Processing:

   • Go to Processing Download and install it.

2. Import the Processing Code:

   • Access the Processing code from Pastebin and paste it into a new Processing sketch.

3. Configure the COM Port:

   • Ensure you select the correct COM port in the Processing code to match your Arduino.

4. Run the Processing Sketch:

   • Execute the Processing sketch to visualize the sonar readings.

Step 6: Testing the Sonar System

1. Power Everything On:

   • Connect your Arduino to your computer or a power source.

2. Observe the Output:

   • Move an object within the sensor's range and watch the output in the Processing window.
   • The servo motor should also move according to the detected distance.

Conclusion

Congratulations! You've successfully built a functional ultrasonic sonar system using Arduino. This project not only enhances your understanding of electronics and programming but also serves as a foundation for more advanced projects. Consider exploring additional features, such as integrating an LCD display or adding more sensors to expand your sonar system capabilities. Happy DIYing!
