Esp 32 camera-Module. Servo controll

Projects Programming
1

Hi I'm working on a RC car with the esp 32 camera Module as an fpv camera.
But I was not able to control the motors of the car over the internet,
the same time as the esp 32 cam was streaming a video.
As the controller I'm using my phone which opens an URL/"command".

does anyone know how to do that?

I have not tried servos and I don't know if they work with a 3.3v signal.

I have made a simple FPV controlled model train using an ESP32-cam controlling a DRV8833 motor driver. I could see the image on my phone or tablet and control the speed and direction.

Please post your program and also give details of the all the connections and exactly what the ESP32 is connected to.

Im using the esp cam example code with a esp32 cam Thinker Module. But I dont know how to create the code that controlls the servomotors.
Not even whitch library I can ore have to use.

I have a 3.7V batterie connected to the 3.3V pin and the servomotors to pin 14 and 3.

Olso I tested the servosmotors and they do work on 3.3V.

Interesting. But I can't help if you don't post the program. Though my experience with the ESP32 CAM is limited and I am not guaranteeing that I an solve your problem.

I'm using the example code "Camera Web server", which is included in the Arduino IDE,

( File - Examples - ESP32 - camera - CameraWebServer )
to stream the video, but I don't know how to send data to the esp the same time as streaming a video.

I suspect that program does not control servos and that you have made changes to it for your project.

Please just post your program. Also, people may be able to help you even though they don't have the ESP32-cam software in their IDE.

This is the same request that I made to you in Reply #1.

There is a "Read this before posting a program question..." at the top of the post list you need to read. It tells how to post the code you are using for evaluation. Also most hobby servos are spec. at a minimum operating voltage of 4.8v.
