ESP32 Cam with Arduino

Hi ,
I am trying to program ESP32-Cam by Arduino UNO but unforsionatlay it was not working.
This error message displayed to me while trying uploading the code :
esptool.py v3.3
Serial port COM3
Connecting......................................

A fatal error occurred: Failed to connect to ESP32: No serial data received.
For troubleshooting steps visit: Troubleshooting - ESP32 - — esptool.py latest documentation
the selected serial port For troubleshooting steps visit: Troubleshooting - ESP32 - — esptool.py latest documentation
** does not exist or your board is not connected**

By the way I connected the ESP32-CAM with Arduino same like this diagram in this link:

Did you put the ESP32-CAM into upload mode before trying to upload?

Do u mean by pressing RST Botton ?

No, you need to connect GPIO0 to GND and then press the reset button on the ESP32CAM.

If you open up the Arduino IDE Serial monitor (before you press the reset button) you should see a 'Waiting for Download' message when you press the reset button.

At @srnet saud... GPIO0 needs to be pulled to GND and THEN reset the ESP32CAM... that puts it in upload mode.

Thanks, The code was uploaded right now

But since I am using CameraWebserver example , the link which they give it to me not working

what link?
