I am getting an error message ‘camera capture failed ‘

Hi.
Since you tested each component individually, and they are working, I think it must be a power issue.
You may need to power the motors using a separate power source.

Hello,
Seems to be 2 different issues,
Pressing the Up and sometimes the Down
Gives the error message ‘camera capture failed ‘
and from that moment on, there is no video.
Gave the servo a separate power source,
connected the grounds of course,
They still refuse to move.
very strange…..

I’m sorry but I don’t know what might be wrong.
We tested the project multiple times and it worked fine. Additionally, other readers have also tried the project successfully.
What motors do you have?

Yes, I understand,
Actually it did work for me once,
and I can’t understand what has changed….,
Thank you for trying.

Hello again,
So, I know when servos stop reacting,
it is after running esp_camera_init(&config)
in the setup().
Before this command servo works, after it doesn’t.
Maybe you could help from here

What ESP32-CAM are you using?
The ESP32 uses some PWM to configure the camera.
We wrote the code so that it doesn’t interfere with the PWM on the motors.
Did you change anything on the code? Does your ESP32-CAM have a different pinout?

Hello Sara,
That’s it, Problem solved 🙂
I opened my old laptop and uploaded the program from there,
and it works like a charm 🙂
I suspect the problem had to do with the version of ESP32_SERVO,
here I used the older version 0.7
On the first computer, I updated the library to 0.11,
But even after returning it to 0,7 the problem continued,
so maybe somewhere something stuck…..
Thank you very much for your support.
Regards

Hi.
Weird. Maybe you have two different (but very similar) libraries installed?
That’s very difficult to find out what might be causing that issue.
At least, now we know that the project is working.
