CIPAD: Micro Servo Moteur
Table of Contents
Introduction
This tutorial provides a comprehensive guide on using a micro servo motor with Arduino, as demonstrated in the video "CIPAD: Micro Servo Moteur" by Daniel Talbot. The tutorial is designed for beginners and will help you understand the basics of controlling a micro servo motor, along with practical tips for your projects.
Step 1: Gather Your Materials
Before you start, ensure you have the following components ready:
- Arduino board (e.g., Arduino Uno)
- Micro servo motor
- Jumper wires
- Breadboard (optional for easy connections)
- Power supply (if needed)
Practical Tips
- Make sure your servo is compatible with the voltage output of your Arduino.
- Check if you need an external power supply for the servo, especially if it requires more current than the Arduino can provide.
Step 2: Wiring the Micro Servo
- Connect the servo motor’s red wire to the 5V pin on the Arduino.
- Connect the black (or brown) wire of the servo to the GND pin on the Arduino.
- Connect the yellow (or orange) wire (signal wire) to a PWM-capable pin on the Arduino (e.g., pin 9).
Common Pitfalls
- Ensure that connections are secure and correctly oriented to avoid damaging the components.
- Double-check the pin numbers if your code doesn’t work as expected.
Step 3: Writing the Code
- Open the Arduino IDE on your computer.
- Start a new sketch and include the Servo library by adding the following line at the top:
#include <Servo.h>
- Create a Servo object:
Servo myServo;
- In the
setup()
function, attach the servo to the pin you used in your wiring:void setup() { myServo.attach(9); }
- In the
loop()
function, write commands to move the servo:void loop() { myServo.write(0); // Move to 0 degrees delay(1000); // Wait for 1 second myServo.write(90); // Move to 90 degrees delay(1000); // Wait for 1 second myServo.write(180); // Move to 180 degrees delay(1000); // Wait for 1 second }
Practical Tips
- You can adjust the angles and delays to create different movements.
- Experiment with different PWM values to see how the servo reacts.
Step 4: Uploading the Code
- Connect your Arduino to your computer via USB.
- Select the correct board type and port in the Arduino IDE.
- Click on the upload button (right arrow icon) to transfer the code to the Arduino.
- Observe the servo motor's movements as it executes the code.
Troubleshooting
- If the servo does not move, double-check the wiring and ensure the correct pin is used in your code.
- Make sure the Arduino is properly powered.
Conclusion
In this tutorial, you learned how to set up and control a micro servo motor using Arduino. You gathered the necessary materials, wired the components correctly, wrote and uploaded a simple code to move the servo, and explored practical tips along the way.
For next steps, consider experimenting with different servo positions and integrating sensors to create more interactive projects. You can also access additional resources and projects on platforms like Tinkercad to enhance your learning.
