Can I use esp32 cam without connect rx,tx on arduino uno?

Using Arduino Project Guidance

Most probably because the project started with an Uno and now he wants to add image.

If you go to this other post, you´ll see that OP wants to add 3 MG996R servo motors to the project.

So, he has 3 medium servos and 2 DC motors, thus 7 GPIO pins at least to control. He´ll need two more PWM pins to be able to control speed. ESP32 CAM doesn´t have all those pins available.

There are more points to be discussed regarding this project, from powering to connection:

  • ESP32 is a 3V3 device while the rest of the project is 5V native;
  • If he uses Bluetooth to connect to the ESP, he won´t be able to use wifi (IP Camera) at the same time;

I can foresee some difficulties, but I don´t have enough experience to suggest best solution. Maybe it´s better having ESP32 CAM working independently from Uno, as @UKHeliBob suggested.

I´m not sure if the mobile app can deal with BT and IP connections at the same time either.

@nazrulalzam , if you don´t mind, please share how you decided to go on and if it solved your problems. :wink:
