Hello everyone,
I'm currently working on my college project that involves capturing images or video. I'm considering using an Arduino UNO for this purpose and would like to know if it's possible to connect a camera directly to the Arduino UNO. If so, could you please provide guidance on which camera modules are compatible and how to interface them with the Arduino UNO?
Additionally, I would appreciate any tips on libraries or example code that could help me get started with capturing and processing images using the camera module connected to the Arduino UNO.
Thank you

Connecting a camera directly to an Arduino UNO is challenging due to its limited processing power, memory, and data transfer capabilities. It is not well-suited for handling image or video data, as it lacks the necessary resources to process large amounts of data efficiently. However, there are a few camera modules that can be used for basic image capturing, although the functionality will be quite limited. Also, its very difficult to interface them with UNO.
The two camera modules supported by UNO, as far as I know, are:
- OV7670 Camera Module: Limited to very low resolutions (640X480 px maximum). The Arduino UNO's limited SRAM (2 KB) restricts the ability to capture and store high-resolution images.
- ArduCAM Mini: Designed specifically for low-power microcontrollers like the Arduino but is very costly. These modules come with built-in memory (FIFO buffer) that allows the Arduino to offload some of the image data storage and processing to the camera itself.
