final exam..

Temporary stop for final exam for two week..

draft oh draft..

I'm start in doing draft for chapter 1 and 2 which is introduction and literature review and . This draft is for my thesis. I need to submit this draft by week 13.

program...

i'm still in progress to make a program for this project..

Design the circuit

Design the circuit in the proteus. All the circuit design in proteus is connected to the PIC16F877A. Then, search for the program to run the system. The PIC16F877A then will connected to the XBee using the previous circuit in previous assignment. Circuit above is about running light with different type of colour. This running light can be function at the personal room or as a sleeping light. I will add other application such as dimmer so that the user can control the dimmer of light using remote control.

Block Diagam and Flow Chart

Block diagram of this subject

This block diagram represent the flow of circuit that is used inside the remote and at the home application such as fan, light, home ventilation, or home surveillance.

Flow chart of this project

This flow chart represent the flow the systems of this project. From this flow chart, you can design the program for this project.

Overall costing of this project

This are the estimate cost that will be used in this project. This cost planning is approved by my supervisor. For IC socket and IC programmer, I already explained in the previous post in the CCS C compiler title. It is not necessary for you to buy the IC socket and IC programmer per person if you're working in the group but this things are important if you want to learn programming by your own.

Interface between SKXBee and Microcontroller

The PIC16F877A need to be interface with the SKXBee module or XBee chip because XBee chip design is not in the Proteus 7 Professional library. The microcontrollers that has USART peripheral only can interface with the SKXBee.

Picture above shown the schematic diagram to interface the PIC16F877A and SKXBee (XBee chip). All the connection are right. For the push button, it is depends on you whether you want it or not. This push button is a reset button, its function when you want the microcontroller to reset SKXBee during a run time.

But please remember DO NOT connect USB to SKXBee if it is connected to the microcontroller. SKXBee can only be connected either with USB cable or microcontroller.
