Hi, I have a physics project where I have to make a vehicle that stops before it hits a wall. It is a combination of speed and being able to stop before you hit the wall. If you are using electric motors, the limit is 6 volts, I have 2 3-volt motors, 4 AA batteries with a holder, and a switch, but I am unsure how I would make it stop before it hits the wall. I was thinking of having some kind of timer that keeps it running but I have no Idea how to do that or what I would have to buy. Thanks in advance.
