Rc bus project need code

Hi everyone I am making a bus with pvc. I collected all the parts but need some code for my Arduino nano.

Where’s the power coming from ?

Have you drawn an annotated schematic of how it all goes together ?

Have you written any code to test individual parts, or drafted a requirements doc for what it has to do ?

Power comes from motor driver 11.1volt and distribut 5v to Arduino and bt.but code required for Arduino to use for my rc bus

You need to post your code in code tags, and a legible photo of a labelled hand drawn schematic. Advertising pictures tell us nothing.

Is bus a vehicle or a mechanism to connect several wires. What is pvc?

For some parts the IDE example code collection could be useful.
Looking for projects using one of Your parts might give You some code to start from. Do that for all the parts.

Forum will not give You any ready code unless You post in the section for paid work, and pay. What's Your budget?
