文献1:
This project aimed to develop a wireless system to detect and allow only the authorized persons.The system was based on Radio Frequency Identification (RFID) technology and consists of a passive RFID tag.The passive micro transponder tag collects power from the 125 KHz magnetic field generated by the base station,gathers information about the Tag ID and sends this information to the base station.The base station receives,decodes and checks the information available in its Database and Manchester code was used to send those information.The system performed as desired with a 10cm diameter antenna attached to the transponder.The Base Station is built by using the Popular 8051 family Microcontroller.It gets the tag ID and if the tag ID is stored in its memory then the microcontroller will allow the person inside.
RFID Reader Module,are also called as interrogators.They convert radio waves returned from the RFID tag into a form that can be passed on to Controllers,which can make use of it.RFID tags and readers have to be tuned to the same frequency in order to communicate.RFID systems use many different frequencies,but the most common and widely used Reader frequency is 125 KHz.

Choose controller according to your requirements of program memory(flash),RAM,ADC,EEPROM.16kB of flash is sufficient to implement floodfill algorithm.If you are thinking of implementing floodfill algorithm then 256 bytes are required to store Map of the maze and 512 bytes are required for processing so you need atleast 1kBRAM to implement floodfill.ATmega16,32 and PIC18f452 are some controllerspopularly used in micromouse.If you are thinking of building just a wall follower then simple 8051 based controller likeAT89s52 can also be used.Stepper driving:Please read http://www.triindia.co.in/resources/?p=40 a step by step stepper motor guidefirst.There are two types of motors a) unipolar b) bipolar.Unipolar stepper motors can be used as bipolar steppers so prefer unipolar whilepurchasing stepper.You can use simple ULN2803 IC the circuit can be found in 8051 microcontroller by Mazidi.ULN2803 has eight darlington pair in a single package.It hascurrent carrying capacity of 500mA.so it will get heated up frequently will get damaged.So two ULN2803 can be connected in parallel to fix the problem but this is a chalta haiway of driving stepper.

Stepper Motor Advantages
and Disadvantages
Advantages
1.The rotation angle of the motor is
proportional to the input pulse.
2.The motor has full torque at stand-
still (if the windings are energized)
3.Precise positioning and repeat-
ability of movement since good
stepper motors have an accuracy of
3 – 5% of a step and this error is
non cumulative from one step to
the next.
4.Excellent response to starting/
stopping/reversing.
5.Very reliable since there are no con-
tact brushes in the motor.
Therefore the life of the motor is
simply dependant on the life of the
bearing.
6.The motors response to digital
input pulses provides open-loop
control,making the motor simpler
and less costly to control.
7.It is possible to achieve very low
speed synchronous rotation with a
load that is directly coupled to the
shaft.
8.A wide range of rotational speeds
can be realized as the speed is
proportional to the frequency
