Hey, I am trying to code a simple rc car to which i have wired my arduino. I cannot however get it to do anything with my coding. If any of you can help me that would be awesome. What I would like it to do is travel a certain amount of time and then stop. I have it wired up just like adafruit did in their example (ATTACHED BELOW). I have gotten the car to run without stopping, however that is what I really need help with, getting the car to go for a certain period of time and then stop completely.
