Poor image quality issue of OV5640 solved

A project log for ESP32-CAM emails picture

ESP32-CAM sends email with a pic attached every half hour while we are away and if it's bright enough. Now includes servo to move cam.

***SOLVED***  under camera_config change: config.xclk_freq_hz = 6000000; // was 20000000

This also reduces the frame rate.

Still not sure if the 5M higher res and wide angle is worth upgrading from OV2640 to OV5640.
