OV7670 ARDUINO CAMERA PROJECT

Electronics projects like movement and obstacle detection, drones, and robots require a camera for capturing images. I personally recommend using a Raspberry Pi or BeagleBone Black for these kind of projects because the Arduino doesn’t have enough juice to handle the complexities of pictures and, more so, videos. However, if the project doesn’t require a high resolution image then the OV7670 camera module might be for you. This arduino camera tutorial features such camera and how you can use it to capture VGA-sized pictures. I managed to buy a OV7670 camera module that looks like this:
Some modules contain 16 pins; these lack the RESET and PWON pins. Since I own the 18-pin OV7670 module, the rest of the tutorial will be based on such module. If you noticed, the OV7670 camera module has a serial data and clock pin. This means that the Arduino can communicate with the module using I2C. Also, the module operates on 3.3 V so if we are to send data to the OV7670 from the Arduino, we must use a voltage divider to bring the level down. Here is a common wiring diagram used to build an Arduino camera using the OV7670 camera module:

Note that there is no efficient way for the Arduino to display the captured image. What it only does is command the module to take a picture, acquire the image and then send it to a computer via the Arduino’s USB port. Thus, you need to have another application that will display the image from the USB port to your desktop computer. Here is a code to be used to capture an image using the Arduino and OV7670 camera module:
