THANKS YOU IN ADVANCE

A manufacturer of coloured buttons has commissioned you to design, build and install a system for detecting and counting only the white buttons coming off a production line. This system is to be used as buttons of all different colours travel together towards the packing area on a conveyer belt. The number of white buttons detected is to be shown on a digital display. i) Design the detecting and counting system using a PIC 16F1938 Microcontroller, an infrared transmitter & receiver, or photo diode, comparator, some form display (7 segment display), and any othe suitable components you think are required. Write a C program that will display the total number of white buttons. Implement the seven-segment display decoder in software.
