Microcontroller Based Sequential Timer for DC Motor Control

In most of the manufacturing industries, it is required to rotate DC/AC motor forward and reverse alternatively for desired time. First motor rotates forward (clockwise) for some time (say few minutes or even seconds). Then it stops for some time. Again it rotates reverse (anticlockwise) for some time and stops. This process continues. For example, in automated bottle filling plant, the bottles are moving on conveyor belt. When it comes under filler, the filler comes down (that means motor attached with mechanism rotates forward) then it fills the bottle (that means motor stops) again it goes up (motor rotates reverse) and stops until next bottle arrives. For moving filler up and down the time of rotating motor forward and reverse is calibrated and fixed. Also the motor stop time is calibrated based on time required to fill the bottle and the next bottle arrives.
