Hi,
For a school assignment we must make a circuit that can raise and lower a barrier arm using a voltage drop that includes a LDR, a Picax 08M chip, a motor and a transistor (or 2) used as a switch. I know how to set it up so it can raise the barrier arm but I don't know how to reverse the motor without having to rewire it every time or using a switch. I have this idea

but i'm not sure it will work. If it will not can someone please send in a design of a circuit I can use.
Thanks
