You are required to design an embedded system for a milk production line in a factory. A motor will control a conveyor belt that runs for 4 seconds to position five bottles under five nozzles. The belt will then stop and the nozzles will be energized to dispense liquid into the bottles at a fixed rate of 50 ml per second. The bottles are all 500 ml. After dispensing, five motors will start to place the bottle caps. These motors will move down to place the caps and then retract up after the caps are in place. The belt will then run again for the next three bottles to be processed. A warning LED will be used while the belt is running. Two buttons will be provided to start or stop the system, and two more in case of emergency (emergency and reset).

(a) Design the FSM of the system.

(b) Design the hardware schematic of the system.

(c) Develop the code to control the production line.
