Evolution of Microprocessor It is interesting to note that the microprocessor had existed for only 10 years prior to the creation of the PC! Intel invented the microprocessor in 1971; the PC was created by IBM in 1981. Now more than 20 years later‚ we are still using systems based more or less on the design of that first PC. The processors powering our PCs today are still backward compatible in many ways with the 8088 that IBM selected for the first PC in 1981. November 15‚ 2001 marked the 30th anniversary

password using 8051 microcontroller (AT89C51) Summary An electronic lock or digital lock is a device which has an electronic control assembly attached to it. They are provided with an access control system. This system allows the user to unlock the device with a password. The password is entered by making use of a keypad. The user can also set his password to ensure better protection. The major components include akeypad‚ LCD and the controller AT89C51 which belongs to the 8051 series of microcontrollers

interfacing it with 8051 microcontroller through 8255 peripheral. There are 8 select channels‚ IND to IN7 through which we can provide an analog input to ADC which we have obtained from an analog device. This output can be electrical signals of transducers measuring temperature‚ depth‚ pressure‚ etc. in the form of an output voltage. We see that there are 8 input channels for ADC and we can use 8 different inputs at a time. Now the output of this ADC is fed into the input of 8051 micro controller.

CHAPTER 1 INTRODUCTION 1.1 ABOUT THE PROJECT Independent mobility of visual impaired is difficult. Generally‚ to explore the space‚ sightless people use other senses (i.e. hearing‚ touch and smell) to compensate their disability. In familiar settings they learn how to orientate in the spaces by recognizing known features (points of reference). Nevertheless In unknown environments‚ navigation often becomes harder or even dangerous. Besides‚ in pre-designed environments
