I am currently working on a project to install a keypad on my door that will lock and unlock my door if the correct combination is typed into it. I have everything working except I am having problems getting the circuit to reverse the motor, which would unlock the door. I have been looking into using an H-Bridge but would like something more compact that will fit into the relatively small area of my door lock. Any ideas on how I could get the motor to unlock my door?
