Poster for Presentation

finalize.. poster after 2 time repairing with supervisor and CO-supervisor



.....................................................good luck presentation................................................

checking result

figure: IR sensor not detected & LCD will display "RFID parking system"

figure: when a car moving little forward, IR detected and we can see green light glow up. LCD will display "welcome"

figure: when a users touch RFID tag to RFID reader then LCD will display car number plate and amount crdt inside RFID tag.&& gate will go up (OPEN)

circuit diagram and component



figure: circuit diagram for pic

component discribtion

1. power supply
figure: This is a regulator power supply to + 5v.maximun flow to this regulator is 1amp.

2.  Xtal ceramic 4MHz
figure: Pictured above is a ceramic resonator for a timer for PIC. Ceramic resonator in use is 4Mhz.Ceramic resonator must be used to enable PIC 16F873A / maximum 16F877A for ceramic resonator in use is 20MHz.


3. lcd 16 bit

figure: LCD in use is measuring 16x2. The objective in use is to display the results in the programming examples such as display temperature, time and etc.LCD has a 16-foot (pin).
Adjustable resistors (preset) (the 1K -10K) is used to change the brightness level of the display writing, by the way be connected to the LCD 3 feet.

15 and 16 feet for LCD is light (LED) LCD.resistor on leg extensions 16 are used to limit the LED current to prevent damage.

figure: open MPLAB IDE

figure: progamming for pic 16F877

Visual Basic

install Visual Basic V6.0


setup the Visual Basic 6.0 to my computer.



designed for admin log in id and password by the visual basic system

complete admin login id and password, and make coding:


;.............................if button cancel was clicked....................................;

Private Sub cmdCancel_Click()
    'set the global var to false
    'to denote a failed login
    LoginSucceeded = False
    Me.Hide
End Sub
;................................if button login clicked...............................................;
Private Sub cmdOK_Click()
    'check for correct password
    If txtUserName = "Admin" And txtPassword = "12345" Then
        'place code to here to pass the
        'success to the calling sub
        'setting a global var is the easiest
        LoginSucceeded = True
        Me.Hide
        Form1.Show
    Else
        MsgBox "Invalid Username and Password, try again!", , "Login"
        txtUserName = ""
        txtPassword = ""
    End If
End Sub

;............if wrong password = invalid username and password...............;



simulate for VB, log id :Admin & password : 12345


database for vehicle. admin can register a vehicle and topup amount credit of RFID tag.

database for vehicle. transaction of vehicle go in and go out amount of charges.
