Remote control car not moving

I don't know what could have been the problem of my car it not moving after I uploaded my code on Arduino UNO,I am also using H bridge motor driver and battery with IR receiver and remote.i don't know what could have been the problem.

Hey could you reread your post and put yourself in the position of someone trying to help with a possible: electronic, coding or other issue but have no historical information or even idea except your list of parts?

For help please provide the information needed to diagnose an issue. It may mean pictures, wiring or circuit diagrams and codes. A description of what you’re trying to do and whether it worked in the past would be helpful.

Good luck.

OP, you might want to read this thread, once you have, please try your request for help again.

Hey Mr. Service Tech, my car is broke down over in the next town. What is wrong with it?
It has an engine, ECU, and battery.
