i tried to make car central locking,in that i use 4 actuators(door gun) which up and down and make doors lock/unlock.
so this work done by dc motors .so what is shud do to control these dc motors ..
i shud any ic to control these motors or what methos wud be more appropriate.AND IF SUPPLY contiNue to these motors to lock then it consume power more because in while current is continuing in motor to move in direction to lock....
i really geting puzzled wid this problem plz solve ....
 

thaat motors are driven directly by DC voltage ( take from battery ).
You need estimate timming to drive it based on observation.
At least I done this way with no more science.

Sequence of operations must be programmed in a microcontroller.
Is easier than implement sequencing by hardware components.
