    INTRODUCTION:
    The main aim of this project is to provide hazard free vacuum path for blind people through obstacle sensing using microcontroller and sensor .Since sometimes blind people collide against high and moving obstacles, we need obstacles, we need obstacle-sensing function in front of the blind people .this paper proposes a method obstacles of point to point distance measurement using ultrasonic for excellence stick in order to detect moving and high

    CURRENT STATUS:
    Studied about my project and collected all the requirements needed for it . Designed the power supply circuit to obtain 5 Volts output.. Corrected the errors which occurred after designing it. Partially studied about the AT80s52 microprocessor.

    Till here I have completed my project with the help of my guide, and still some part of microprocessor and studying about the voice IC ,program code ,interfacing is left. Which i will complete it as soon as possible.

    MICRO CONTROLLER 89S52:


    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 Atmels highdensity non-volatile memory technology and is compatible with the industry-standard 80C51 instruction set and pin out. The on-chip Flash allows the program memory to be reprogrammed in-system or by a conventional non-volatile memory programmer. By combining a versatile 8-bit CPU with in-system programmable Flash on a monolithic chip, the Atmel AT89S52 is a powerful microcontroller which provides a highly-flexible and costeffective solution to many embedded control applications. The AT89S52 provides the following standard features: 8K bytes of Flash, 256 bytes of RAM, 32 I/O lines, Watchdog timer, two data pointers, three 16-bit timer/counters, a six-vector two-level interrupt architecture, a full duplex serial port, on-chip oscillator and clock circuitry. In addition, the AT89S52 is designed with static logic for operation down to zero frequency and supports two software selectable power saving modes.The Idle Mode stops the CPU while allowing the RAM, timer/counters, serial port, and interrupt system to continue functioning. The Powerdown mode saves the RAM contents but freezes the oscillator, disabling all other chip functions until the next interrupt for hardware reset.

    AT 89S52 Features: Compatible with MCS-51 Products


    8K Bytes of In-System Programmable (ISP) Flash Memory Endurance: 1000 Write/Erase Cycles 4.0V to 5.5V Operating Range Fully Static Operation: 0 Hz to 33 MHz Three-level Program Memory Lock

    256 x 8-bit Internal RAM 32 Programmable I/O Lines Three 16-bit Timer/Counters Eight Interrupt Sources Full Duplex UART Serial Channel Low-power Idle and Power-down Modes Interrupt Recovery from Power-down Mode Watchdog Timer Dual Data Pointer Power-off Flag Fast Programming Time Flexible ISP Programming (Byte and Page Mode) Green (Pb/Halide-free) Packaging Option

    PIN CONFIGURATION:

    Conclusion:
    Till here I have completed my project and still around 40 to 45% is left .so I will b completing it before my third review.
