Description

The attendance system is basically an embedded one. Embedded stands for ‘hardware controlled by software’. Here, the software using a Microcontroller controls all the hardware components. The microcontroller plays an important role in the system. The main objective of the system is to uniquely identify and to make attendance for a person. This requires a unique product, which has the capability of distinguishing different person. This is possible by the new emerging technology RFID (Radio Frequency Identification). The main parts of an RFID system are RFID tag (with unique ID number) and RFID reader (for reading the RFID tag). In this system, RFID tag and RFID reader used are operating at 125KHz. The EEPROM used for storing the details has the capability of storing 256 person details at a time. The PC can be used for restoring all the details of attendance made. This report provides a clear picture of hardware and software used in the system. It also provides an overall view with detailed discussion of the operation of the system.

@sachinmm The 8051 timer can't do 1 second. It can do 50ms so count 20 times

@ExperimenterUK okay thank you...but now I already complete and my dot matrix already light up but when i send message from pc to my hardware project it doesnt show any message on my dot matrix..its only blinking when i click send message....I really dont know whats the problem...I had follow all the steps...schematic and use the coding that have been provided..is it because firstly i had wrong burn the coding in AT24C16?? Is that effect ????
