Arduino Camera OV7670

It’s commonly used with microcontrollers like Arduino, STM32, and others for projects such as visitor monitoring systems, surveillance systems, and more

• Resolution: 640×480 VGA
• Frame Rate: Up to 30 frames per second (fps)
• Power Supply: Operates on a single 3.3V power supply
• Image Sensor: 0.3-megapixel CMOS color camera
• Lens: Equipped with a high-quality F1.8 / 6mm lens
• Image Processing: Includes features like automatic exposure control, automatic gain control, automatic white balance, and noise reduction
• Interface: Controlled via Serial Camera Control Bus (SCCB), which is an I2C interface

• Components Needed:

  • OV7670 camera module
  • Arduino Uno (or compatible board)
  • Breadboard
  • Jumper wires
  • Resistors (10kΩ, 4.7kΩ)
  • Serial Camera Control Bus (SCCB) library for Arduino

  • Steps:

    1. Power Supply: Connect the OV7670 module to a 3.3V power supply. The OV7670 operates at 3.3V, so it’s important to avoid using 5V from the Arduino directly.
    2. Ground Connection: Connect the ground (GND) pin of the OV7670 to the ground (GND) pin on the Arduino.
    3. Power Connection: Connect the 3.3V pin of the Arduino to the VCC pin of the OV7670.
    4. I2C Interface: Connect the SCCB pins (SIOC and SIOD) of the OV7670 to the I2C pins (A4 and A5) on the Arduino.
    5. Clock Signal: Connect the clock pin (CLK) of the OV7670 to a digital pin on the Arduino (e.g., pin 13).
    6. Data Signal: Connect the data pin (D0) of the OV7670 to another digital pin on the Arduino (e.g., pin 12).
    7. Frame Sync: Connect the VSYNC pin of the OV7670 to another digital pin on the Arduino (e.g., pin 11).
    8. Horizontal Reference: Connect the HREF pin of the OV7670 to another digital pin on the Arduino (e.g., pin 10).

    9. Arduino Code:

       You’ll need to use the SCCB library to control the OV7670 and capture images. Here’s a basic example to get you started:

       cpp

       #include <Wire.h>
       #include <SCCB.h>
       
       void setup() {
         Wire.begin();
         SCCB.begin();
         SCCB.setAddress(0x42); // Set SCCB address of OV7670
         SCCB.write(0x12, 0x80); // Example SCCB command
       }
       
       void loop() {
         // Your code to capture and process images
       }
