My car only moves when it is plugged directly into both my pc and battery pack? 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 best thing you can do is post a schematic, not a frizzy thing along with a picture of the parts that you modified and links to all of the other parts. You state: &quot;orange arduino led is flashing and making a weird sound&quot; How does a LED make a sound, they are not designed to. The best thing you can do for yourself is read the Arduino cookbook and do some online tutorials on basic electronics and the arduino.
