Camera OV7670 on an Arduino UNO

Other Hardware Sensors
1

Hi,

Although I'm an engineer, I'm new in electronics and this beautiful world of Arduino.

I am planning to do a project which consists on a PIR sensor that triggers a OV 7670 camera module, so that it captures a picture of the thing that is moving in front of the PIR.

The problem comes when I want to connect the OV 7670. I don't know how to connect that camera to Arduino UNO, and I don't know what it pin means.

If someone could just help me out with this I'd be very thankful.

:slight_smile:

You can look at this thread, but all it'll show you is what a horrendous PITA it is to try and deal with that camera.

Thank you very much!. What camera would you recommend me?

Take a look here. I've just started playing with the Arducam-Mini, and made 10X more progress in just a few days, as compared to endless hours spent screwing with the OV7670.

And here. There are 2M and 5M pixel versions.

One big advantage is the Arducam guys have done all the nasty work of figuring out the best way to set the 200 or so registers in the Omnivision cameras. I spent weeks playing with those values myself on the OV7670. A further advantage is, the OV2640/OV5640 chips used in the Arducams have JPEG built-in, so you get nice compact storage of images for archiving. But, as related on my other thread, you can also use the BMP mode for custom image-processing, if you need to do so.

Oh my God, you are my salvation. Jajajajaja

I'm from Spain, so it is quite late now to start chatting in here, but...could I have a contact from you (email or something) so that you can help me or guide me?.

Thanks again!!! :sunglasses:

L_G, if you're just getting started with Arduino, it's easiest to go with an UNO board at first, and learn the basics. Write a few programs, blink a few Leds, do some Serial communications.

Then, once you're getting familiar, the Arducam-Mini will plug right in and go. In general, the UNO is underpowered for image processing, especially due to having only 2KB of RAM, but the Arducam-Mini was designed to easily interface with the UNO, so it's very little trouble.
