Throughout this week, I only focus on constructing PIC circuit. Of course it is not as easy as A, B, C but since I seek helps from my friends, I am able to construct the PIC circuit within one week. At first I doubt that the PIC circuit will work correctly, but after a few try and error, I finally success in constructing it. The circuit works fine and hopefully there will be no error afterwards. This PIC circuit is to interface the RFID reader with the computer and display at the LCD like a date, time and name of the student.
Below is the PIC 16F877A circuit:
