WEEK 7

                                                Scope of Work

     This project will focus primarily on circuit construction such as PIC16F877A as the microcontroller, LED as power indicator, 4x4 keypad for keying in password, ICSP (In Circuit Serial Programming) for loading program, and push button as input for PIC microcontroller. With my latest creations, you can access all projects such as system password using only the keypad of any cell phone, never mind common type of wireless or touch screen using sensor detection device creation. So we can make this system without the need for a keypad button again and replace it with a cordless device and can also be hidden for specific use. This model function remote uses radio frequency medium for transmitting data to the reciever and microcontroller circuit.  Second, this project will also focus on LCD screen display which is used to display words and password symbols. 

Finally, relay and buzzer will function as output for this system which can be applied to any daily application such as door lock. Other aspects such as the production and marketing of the password door security system with LCD display will not be covered in this project.
