I need a detailed schematic diagram process of wiring all this components for a non soldering obstacle avoidance robot Components are Arduino, 4 DC motor, l298n, HC-sr04 and HC-05 both on the breadboard, battery casing with two 3.7voltsbatterry and a switch.
Consider asking the moderator to move your post to the Jobs and Paid Consultancy forum section.
Ok how can I do so
Use the flag button at the lower right of the post to send notifications to administrators.
It will require me paying for it right
If so I don't think I will be able
Hi, @akinlatauto19
Welcome to the forum.
Can you please tell us your electronics, programming, arduino, hardware experience?
Is this a school/college/university project?
Thanks.. Tom.. 
Not necessarily, but this is volunteer forum and most forum members don't appreciate unapologetic demands, like the one you posted.
You can probably buy a kit that matches your needs.
Am sorry, have still not being able to change it
First I want to change the post to job and paid consultant section
It is a school project
Show this thread to your class instructor, who will probably help you.
I don't get pls
Thread moved as requested.
Do a search on the web.

Hi, @akinlatauto19
Sorry, It is not that we will not help you, but you must show us your work and attempt at code.
We will help, but not write all your code for you.
We will help you learn and help you to pass your qualification.
BUT
We will not do all the work and have you learn nothing.
Thanks.. Tom..
What should I send, I have the code file and also the project is already completed but I just need a schematic diagram to add to my writeup
Thanks
How did you wire it all together ?
If you already have everything connected and working, just draw it. Pen and paper is willing. Or have a look at one of the many online simulators (e.g. Wokwi); you will have to use one that has all components that you're using.
