The main aim of the project is to design a system using which we can control the speed and direction of the stepper motor by using PC and the microcontroller 8051. The project is designed in such a way that a PC will be interfaced to the controller through serial communication, using which we will input the data to the controller using the hyper terminal of PC to control the motor. Here we will use a serial line driver IC MAX232 to interface the PC with controller. And for the visual effects, the front end will also be developed by using a good user interface software C# .NET to input the data to the controller through serial communication. The application always interact with the serial port. In the C# application we will design the buttons to control the stepper motor with the meaningful labels. So by clicking those buttons, the predefined data will be transmitted to the controller serially. And a stepper motor will also be interfaced to the controller through a driver IC ULN2003A. Now, it is the job of the controller to read the data received from the serial port and to perform the predefined task of rotating the motor clockwise, anticlockwise and increasing, decreasing the speed of the stepper motor. 16X2 LCD is provided at the receiver side to display the status of the DC motor. This project uses regulated 5V, 500mA power supply. 7805 three terminal voltage regulator is used for voltage regulation. Full wave bridge rectifier is used to rectify the ac output of secondary of 230/12V step down transformer.

According to ancient Greek scripts BIOMETRICS means study of life. Biometrics studies commonly include fingerprint, face, iris, voice, signature and hand geometry recognition and verification. Many other modalities are in various stages of development and assessment. Among these available biometric traits Finger Print proves to be one of the best traits providing good mismatch ratio and also reliable. Registering the attendances of students has become a hectic task as sometimes their attendance may be registered or missed. To overcome this problem i.e. to get the attendances registered perfectly, we are taking the help of two different technologies viz. EMBEDDED SYSTEMS and BIOMETRICS. Firstly discussing about Biometrics we are concentrating on Fingerprint scanning. For this we are using FIM 3030N high voltage module as a scanner. This module has in-built ROM, DSP and RAM. In this we can store the fingerprints of up to 100 users. This module can operate in 2 modes i.e., Master mode and User mode. We will be using Master mode to register the fingerprints which will be stored in the ROM present on the scanner with a unique id. The fingerprint module will be interfaced with the microcontroller through serial interface. The images of the students of a particular class will be scanned and stored in the microcontroller. The students have to scan their images to register their attendance daily. When the student has to register his attendance on that particular day, he has to scan his fingerprint image. The fingerprint module scans the student’s image and passes the scanned image to the microcontroller. The controller reads the scanned image, compares this image with the already stored image. If both are matched, the student’s attendance will be registered for that day. If it is not matched, the student’s attendance will be marked as absent and buzzer indication will be given. By simply pressing a switch, we can get the list of absentees for that day. We can see details on 16X2 LCD. (In this project we can connect microcontroller to PC and PC maintain presents and absents list with help of C# application-But it is optional).
