i wanna to do connect between Arduino Mega 2560 and ov7670
i try this connection
with this code
but when i try to run it stop there without and output
Do not post screen shots, never ever post fritzing diagram and google before posting a question.
Mark
PS You wasted your money on the ov7670 you should have googled first!
M
i search on google for more than month without any solution iam a student in IT and i try to solve my problem there if u have a solution help me if not then not write this post.
any way ty for nothing
This page would suggest that you need an interface shield to use that camera with a low speed microcontroller like a Uno.
ty but the "ArduCAM_OV7670_Camera_Playback.ino" is not work can u send me othere link with many thanks for ur time for help me

You may want to read [SOLVED] Problem with camera module OV7670 - Sensors - Arduino Forum where the person got it working.

You may want to read https://forum.arduino.cc/index.php?topic=535819.0 where the person got it working..
ty sir i try it now 
it's not work good the image is not good
up
Omany:
up
Don't do this.
If you want help you need to give more details: all you've said so far is that the image isn't good. If you are using a camera and the image isn't good, do you think the problem is likely to like in the Arduino or the quality of the camera?
