DIFFERENCES BETWEEN PIC 10,12,16 AND 18

DESIGN CIRCUIT USING PROTEUS

Proteus is software for microprocessor simulation, schematic capture, and printed circuit board (PCB) design to co-simulate the complete microcontroller based designs. It is developed by Labcenter Electronics. This is the perfect tool for students to test their microcontroller designs before constructing a circuit in real time. This program allows us to interact with the design using on-screen indicators or LED and LCD displays and, if attached to the PC, switches and buttons.

In summary, Proteus is the program to use when you want to simulate the interaction between software running on a microcontroller and any analog or digital electronic device connected to it.

Proteus PCB design combines the ISIS schematic capture and ARES PCB layout programs to provide a powerful, integrated and easy to use suite of tools for professional PCB Design..

All Proteus PCB design products include an integrated shape based autorouter and a basic SPICE simulation capability as standard. More advanced routing modes are included in Proteus PCB Design Level 2 and higher whilst simulation capabilities can be enhanced by purchasing the Advanced Simulation option and/or micro-controller simulation capabilities.

System components

ISIS Schematic Capture - a tool for entering designs.

PROSPICE Mixed mode SPICE simulation - industry standard SPICE3F5 simulator combined with a digital simulator.

ARES PCB Layout - PCB design system with automatic component placer, rip-up and retry auto-router and interactive design rule checking.

VSM - Virtual System Modelling lets cosimulate embedded software for popular micro-controllers alongside hardware design.

System Benefits Integrated package with common user interface and fully context sensitive help.

BASIC CIRCUIT OF PIC 16F877A

PIC 16f877A

PIC 16F877A is a small piece of semiconductor integrated circuits.. This package is very easy to be soldered onto the stripboard. However using a DIP socket is much more easier so that this chip can be plugged and removed from the development board.

This IC very popular because it very cheap and it easily to find at electronic shop especially at Jalan Pasar.it is also very easy to be assembled and  to make this IC work is need a 5V DC power supply, a 20MHz crystal oscillator and 2 units of 22pF capacitors as it clock.It advantage is this IC can be reprogrammed and erased up to 10,000 times. Therefore it is very good for new product development phase.

VISUAL BASIC

Visual basic is programming language and environment developed by Microsoft. Based on the BASIC language, Visual Basic was one of the first products to provide a graphical programming environment and a paint metaphor for developing user interfaces. Now there are visual environments for many programming languages, including C, C++, Pascal, and Java. 

So in my project I will use visual basic as my programming. The 16F877A will act as a brain for the system and make all the decision based on the programming language. The condition of the farm is display on the computer using Visual Basic (VB). In that list, all information like student name and ID number will attached including the student status and subject. If the there were no match with database, it means that student was in already been bar or have the problem with the finance. When this happen, student cannot enter examination hall by refer at registering form and the information of that student will be update into database. This project will help invigilator taking the student attendance more easily and automatically.

WHAT IS RFID..????

Radio frequency identification (RFID) is a  a system that transmits or receive by the identified in the form of a serial number of an object or person wireless using radio waves. It's can be categories as automatic identification technologies.


RFID is in use all around us.It usually use at booth toll when using touch n go,at super market from scanning the bar code to know the item price and at parking.

RFID technology does not require contact or line of sight for communication. RFID data can be read through the human body, clothing, non-metallic materials and therefore has limitations.

RFID system is often dependant on its application. High frequency RFID systems (850 MHz to 950 MHz and 2.4 GHz to 2.5 GHz) offer transmission ranges of more than 90 feet, although wavelengths in the 2.4 GHz .


A basic RFID system have three components:

• An antenna or coil
• A transceiver (with decoder)
• A transponder (RF tag) electronically programmed with unique information

To get the data stored on an RFID tag, we need a reader. A  reader is a device that has one or more antennas that transmit radio waves and receive signals back from the tag. The reader then passes the information in digital form to a computer system.

INTRODUCTION

My project basically about the RFID that will be using to capture the attendance of student in the exam hall.  By scanning the Id card , the invigilator can identify the status of the student on time.The scanner will transfer the data to PC or Laptop by wireless.So my task this week is to do some research about RFID and wireless.I also must prepare my proposal and submitted to madam Julie by this Friday.
