Week 6 FYP I

Title of activity:

Study of IC and PCB 

Objective: 

1. As the IC should be implanted on the PCB board, we have to study in detail about the IC and another component that will also implanted on PCB.

2. Beside, to study all the outcomes which are for LED, and buzzer.

Content/Procedure:

In Circuit Serial Programming (ICSP)

1. MCLR, RB6 and RB7 need to be connected to the USB In Circuit Programmer (UIC00A) to program the PIC microcontroller. 
2. At the same time, RB3 need to be pull low to 0V to disable low voltage programming, because the programmer is using high voltage programming. 
3. The programmer (UIC00A) is not included in DIY project set since it can be used several time for different project set. 
4. User can also choose other type of PIC programmer to load the program.

The Function of Component on PCB

Component:

1. 2510-02 connector,

(to use either 9V battery or 12V battery to power up the circuit).

2. AC-DC adaptor socket

(to use power supply from AC-DC adaptor).

3. Diode

(to protect the circuit from wrong polarity power input).

4. Capacitor

(to stabilize the input and output voltage of the LM7805 voltage regulator).

5. LM7805

(voltage regulator, supply 5V for PIC).

6. 2510-04 connector for RFID reader.

7. ICSP box header

(to connect to PIC programmer for loading program).

8. Reset button

(to reset the microcontroller).

9. Push button.

10. Power indicator LED

(to indicate the power status of the circuit).

11. LED status indicator.

12. Slide switch

(to ON or OFF the circuit).

13. Buzzer.

14. Preset

(to adjust the brightness of the LCD).

15. Crystal (20MHz).

16. PIC 16F876A

(the main brain of the system).

17. LCD.

Conclusion:

Finish with the searching on IC, PCB and the output.
