I am doing a project on a door shutter opener where there are two states or signal I pass into the circuit:
0V: Door shutter closed
5V: Door shutter opens.
I plan to accomplish this via motor control. The problem is I need to reverse the polarity of motor to change direction so this basically works like a DPDT switch except that I have to do this via electrical signal.
How do I accomplish this and is it possible to do this via transistors or gates?
I've done basic electrical science course in college till now so I would appreciate it if you can talk at my level of learning.
