i built a car that works with four motors,one motor driver(specifically the l293d),the arduino and the battery pack with four AA-Batteries. The motors work fine though, but they only work when it is connected to the laptop and the battery pack.I've also removed the METAL insulation from the copper wire and now it is copper.Sadly i have also connected the two poles together and there was some lightning but no fire thankfully(by accident of course).if anyone else had the same issues and fixed them please contact me. Thank you very much stranger.

    the battery pack came with two copper wires one red and black and then there was some metal at the tip so i removed it to make it longer and now it doesn't work Mar 10 at 18:55
