Introduction

• Lighting System Control consists of a control
  system through a computer, and also by using PIC
  controller, and lights to control with it.
• In our project we take a building of eight floors
  as an example.
• We represent each floor as a LED, And we control
  the light of each floor separately from others

Objectives

• Showing an automatic programmable way for
  lighting the floors in a building .
• An expected floors in the building will switch
  off and switch on in a given time.
• Energy savingto save electrical power from being
  wasted.

6
Hardware Specification

• PIC16F877
• LCD
• LEDs, for specifying the floors
• SP232ACP
• Oscillator
• Buttons
• Capacitors, Resistors
• Regulator

7
Software used

• PIC C Compiler( To write the program to receive
  data and time from the PC Program and control
  through it in the hardware and LEDs).
• Visual C programming (MFC)(To write the program
  required to send data and time to the PIC)

Schematic Diagram

• This diagram in the previous page specify the
  connections with the PIC in every pin which make
  the hardware understood.
• The PIC connects with eight LEDs and the LCD to
  make a relation between lighting the floors and
  showing the results in the LCD ( number of floors
  that switched on or off and the current time
  every minute.

10

• The LEDs are connected with the PIC that are work
  in a programmable way in lighting the floors as a
  systematic method
• The LCD will show the current time, and the
  number of the floors which lighted or switched
  off to give complete information about the
  building lighting in every minute

11
The Mechanism of the work

• We insert the start time, stop time for each LED
  in the PC program
• We Open the serial port
• We transmit these data through the serial port
• We close the port

12
Cont.

• The PIC receives these data
• Storing these data in the EEPROM of the PIC
• We apply the functions in the PIC program on
  these data
• The output will show in the LEDs that are on
  after a given time, or off in a given time

13
PIC Working

• The work of the PIC is receiving data from the PC
  , and stores it in EEPROM with applying some
  functions on these data to switch on and switch
  off some LEDs, and displaying the time ,when
  floors lighted, and when floors switched off that
  will be shown in the LCD.
