Sir,
Actually I'm working with a small project named Collision Avoidance Robot in which two LDR based sensors(Mentioned in the main post) are used One at front side and another sensor at the Back side of a toy car(Having a DC Motor).
I'm controlling the motion(F/w, B/w or stop) of this car by interfacing the sensors o/p to the H-Bridge ckt and hence control the motion of car with the o/p of H-Bridge.
Know I'm facing the problem at this stage and also, just before interfacing the sensors o/p with H-Bridge ckt.
