Dear Hilal Abbood Al-Libawy,

Is the OV7675 planned as a "sensor"? If you are satisfied with a delay of ~0.1...0.3 seconds and more (time to analizing algoritm), then choosing Arduino as a base is justified due to its simplicity, cheapness and availability.

Dmitriy Zhukov, Thanks for your reply. yes you are right that the camera is the vision sensor for object detection algorithm. Do you suggest any algorithm that can fit the resources of the board and work properly with acceptable time ( such as 0.1-0.3 seconds in inference time)

My pleasure ),

I don't know what your task is and what objects you want to detect. But in any case, you won’t be able to get by with this kit alone - the Nano has too little memory to process frames. If you need edge or profile recognition, you can replace the Nano with a Mega or, better yet, an STM32 to capture and transfer frames to a PC and process them there. If "presence" signaling is required, I would use an inductance sensor or an optical rangefinder. Then Nano will be enough.
