FEST UTILITY SOFTWARE
INTRODUCTION

This project is based on VTU syllabus. The proposed system is based on ATMEL 89S52 µcontroller, which is in our syllabus.
For doing this project we use some of the software like
 Embedded C for programming the application software to the microcontroller.
 Protel schematic software is used for designing the circuit diagram for this project.
 Express PCB software is used for designing the PCB for this project.
(Since PCB making is a big process and involves lot of machineries, which are expensive, we are going to outsource this to the manufacturer.)
ABSTRACT
This project is designed in order to play games during fest. In this project smart card is used with nine-point touch screen. Person who wants to participate should have this card; get it recharged for some amount. This eliminates the use of coordinates and volunteers during fest time. The most important of all this is, avoiding all the malpractices done at the time of gaming. Each person has his own smart card, which in turn has a unique ID.
The main advantage of this project is that it displays the current amount and game played. It also avoids hiring of people for counting of amount manually and gives out the result fast.
TECHNOLOGY USED: Smart card interfacing technology.
PERCENTAGE OF SOFTWARE AND HARDWARE USED

Embedded C: 40%
Visual Basic: 20%
Hardware: 40%
COMPONENTS USED
 Power Supply 5v DC - 7805
 Microcontroller - 89C51Atmel (Atmel.Com)
 Crystal - 11.0592MHz
 Smart card - Atmel (2K)
 LCD - Liquid Crystal Display 2X16
 MAX232 - Serial Communication
 Buzzer - Freq-1 to 18Khz.Volt-5V-12VDC
 RF card reader
 Touch screen with 9 touch points.
SOFTWARES USED
 Embedded C
 Visual basic
WORKING PRINCIPLE
Initially the card must be inserted in order to register. Once it is registered it can be used to play the games of his choice. When the card is inserted the command sent through serial port is $,R,12345,A,100,# to VB side ,where $,R, is command and next five characters is card number and ‘A’ denotes the amount card is recharged followed by amount # terminating character. Each time a game is played amount is deducted. Card number can also be given by sending the command $R followed by card number with a terminating character #. Card number is entered through VB software this number is written to the card. Since touch screen is used options can be selected by touching on the touch screen. Process will be fast.
COMPONENT APPLICATIONS
Power supply:

The microcontroller and other devices get power supply from AC to Dc adapter through voltage regulator. The adapter output voltage will be 12V DC non-regulated. The 7805 voltage regulators are used to convert 12 V to 5VDC.
Vital role of power supply in ‘Fest Utility Software’ the adapter output voltage will be 12V DC non-regulated. The 7805/7812 voltage regulators are used to convert 12 V to 5V/12V DC.
Microcontroller:
The AT89S52 is a low-power, high-performance CMOS 8-bit microcontroller with 8K bytes of in-system programmable Flash memory. The device is manufactured using Atmel’s high-density nonvolatile memory technology and is compatible with the industry- standard 80C51 instruction set and pin out.
Features
8K Bytes of In-System Programmable (ISP) Flash Memory
Endurance: 1000 Write/Erase Cycles
4.0V to 5.5V Operating Range
256 x 8-bit Internal RAM
32 Programmable I/O Lines
Full Duplex UART Serial Channel
Fully Static Operation: 0 Hz to 33 MHz
Vital role of Micro controller-AT89S52 in ‘Fest Utility Software’ is used to Control all the operation.
Memory:
These memory devices are used to store the data for off line process. The AT24C02A / 04A/ 08A/ 32/64 provides 2048/4096/8192/32,768/65,536 bits of serial electrically erasable and programmable read only memory (EEPROM) organized as 56/512/1024/4096/8192 words of 8 bits each. The device is optimized for use in many industrial and commercial applications where low power and low voltage operation are essential. The AT24C02A/04A/08A is available in space saving 8-pin PDIP.
Features
Internally Organized 256 x 8 (2K), 512 x 8 (4K) or 1024 x 8 (8K)
2-Wire Serial Interface (I2C protocol)
High Reliability
– Endurance: 1 Million Write Cycles
– Data Retention: 100 Years
– ESD Protection: >3000V
Vital role of External EEPROM memory in ‘Fest Utility Software’ is used to store the card number in smart card memory; the device (microcontroller) communicates with the smart card memory using I2C protocol.
RS 232 CONVERTER (MAX 232N) Serial Port:
RS-232Protocol
RS-232 was created for one purpose, to interface between Data Terminal Equipment (DTE) and Data Communications Equipment (DCE) employing serial binary data interchange. So as stated the DTE is the terminal or computer and the DCE is the modem or other communications device.
