ya.....i'm not using microcontroller to control it.. instead i m using a H-Bridge instead... well....i'm applying it in my project..which is the "Automatic Swing System" Have u seen those playground swings....? my project is based on that concept....the only thing is that it swings back forward automatically.... I'm attatching a circuit which i tot could help me solve my problem.. Can you give me any comment regarding this circuit.... But i was confuse about the operation. For example, if the motor is rotating in clockwise direction, can i immediately change the polarity to rotate it in the opposite direction? By doing so, can the motor be damage due to the immediate change of current? Well i having problem uploading it........ so The_H_Bridge_for_DC_Motor_Control.zip

I'm curently having some problems with the motor application. First of all, the motor i'm currently using is a DC motor. Most probably a 12-24V DC-Motor. The DC Motor should rotate in both back and forward directionn automatically.. Is there any other method to control the change of direction of the motor without involving a microcontroller..? Can any mechanical method involve..?
