METHODOLOGY

This project is combination of 3 method, which are simulation part by using Proteus, programming part of microcontroller system by using PIC C Compiler and hardware part that includes mechanical facilities. In the methodology part here, the block diagram, which represents the relationship between those, is shown together with the process from the beginning of system working in the flowchart.

BLOCK DIAGRAM

From the block diagram, it shows that the Microcontroller act as a main process to control the whole system. For the input parts, it involving 3x4 keypad where by using this components, the user can key in the data of identification number and the number of pages inside the assignments. After that, microcontroller will process the data and give the instructions to the stepper motor to open up the gate of the box. When the user already put their assignments inside the box, then, the LCD will display whether the identification number that has been key in is correct or not. If the answer is yes, the process will go to close the gate and print the receipt. However, if the answer is no, the process will end.
