Hi all,
I am participating in a design challenge where the aim is to build a repeatable vehicle. The vehicle must be fully automated once it has been turned on. The vehicle is also small, being no more than 400x400x400mm.
One main section of the brief is that the vehicle must travel to a wall, reverse direction and return to its original location.
All I need is a simple circuit that will allow for a button to be pressed against the wall which will then reverse the polarity of a small DC motor. I was wondering whether this would be possible with just a DPDT switch, or, because of the motor, a DPDT relay will be needed. I want to keep it as simple as possible, so just the switch would be preferred.
Many thanks.
