Thank you for letting me in.
As a 50 year old man, I started with Arduino about a year ago, but due to my priorities changing, I did not continue. Now I am back!
My project now is to make a robot car with camera, but not using the ESP32 to control it, but rather a RC remote and receiver. Boy, with no XP and no programmming skills, this is so hard. Will get there soon.
Thanks for the support and I will do my best to be interact with everyone
Regards

@xenophon Good luck, lot's here who can help.
Arduino says and I agree, in general, the const keyword is preferred for defining constants and should be used instead of #define

Hi all. Thank you for the warm welcome 🍾
Maybe someone can give some advice.
I am busy with the robot car project. All the content I find connects the serial output of receiver to the Arduino uno. Fine, it works well. I followed another guy's build, where he built a robot car with the ESP32-CAM. Works ok as it is connected with phone over wifi. I found it is not very stable and the range is very limited.
My plan:
1. Use the ESP32-CAM to control a L298N and send only the video over wifi to phone / cloud.
2. Use RC receiver serial output (iBus) to an input (Don't know how or which one) of ESP32-CAM
3. So in some way the ESP32-CAM outputs must go to the L298N inputs.
I first have to know how digital inputs and outputs work.
The reason for me to jump to such an advanced project is to build this project to help my wife when she is alone at home. We have very high crime rate in our area and it is the safest way for her to see what is going on outside the house, without going out (which might be very dangerous especially at night). Our CCTV does not cover all areas and might have blind spots.
Any help to advance this project and the writting of the code will be appreciated so much.

@xenophon When you have concrete plans for us to look at I am sure there are many who will help.
