Tutorial: How to Use OV7670 Camera Module

The OV7670 camera module is ideal for artificial vision and video streaming projects with Arduino. It is perfect for beginners who want to start exploring the world of computer vision.

What you need

• Arduino Uno or compatible
• USB Type B cable
• Power adapter

Steps

1. Connect the Arduino to the computer via USB type B cable.
2. Check the connection between the OV7670 module and Arduino following the instructions on the module labels.
3. Install the necessary serial communication drivers (if required).
4. Load the example sketch provided in the Arduino IDE software.
5. Verify that the OV7670 LED turns on and blinks, indicating a correct connection.
6. Use a software to monitor the Arduino serial console to display the data received from the camera.
7. If necessary, modify the sketch to adapt it to the project requirements.
8. Test the system with different lighting conditions and optimize the settings.

Example code

/*
 * Sketch di base per la comunicazione con OV7670
 */
#include <SoftwareSerial.h>

SoftwareSerial mySerial(10, 11); // RX | TX

void setup() {
  Serial.begin(9600);
  mySerial.begin(9600);
}

void loop() {
  if (mySerial.available())
    Serial.write(mySerial.read());
}
