FYP Sem II : Week 3

Title of Activity:

New Block Diagram 

Analysis:

After changing the automatic component from keypad into RFID, the block diagram is now a little bit different from what I had proposed. Now, it will look like this.

The input part will be:

1. 12V adapter that connected to the main power supply and will be stepped down to 5V by using voltage regulator.

    2.  RFID reader that is used to detect ID of student.

    3.  IR sensor that is used to detect document or assignment into the "Automatic Document Receiver".

    4.  Reset button as the component to reset the whole PIC circuit.

The output part will be:

1. LED, Yellow, Red, Green and Blue that are used to indicate the input part of IR sensor, RFID reader   and On/Off function. 

    2.  Voltage level converter MAX23 will convert signal to be compatible with computer.

Conclusion:

This block diagram will be used to explain how the circuit will be functioning.
