The main aim of the project is to design a alram based alerting system for the blind people .●Ultrasonic Sensor
senses the obstacles in its path by continuously transmitting the ultrasonic waves.●The controlling device of the wholeArduino Nano With Cable ❖Ultrasonic Sensor❖Buzzer ❖Zero Pcb❖Vibration Sensor ❖Battery Cap ❖9 Volt Battery ❖Solder Wire ❖Soldering Iron ❖Connecting Wire. system is a Microcontroller.●This system is very helpful for blind peopl
We are using arduino nano to work with ultrasonic sensor.The length will be comparatively small and it has more memory.We can able to access more equipment'sIt supports all types of sensors
,,,,,,,,The Arduino Nano is a small, complete, and breadboard-friendly board based on the ATmega328P released in 2008. It offers the same connectivity and specs of the Arduino Uno board in a smaller form factor.●The Arduino Nano is equipped with 30 male I/O headers, in a DIP30-like configuration, which can be programmed using the Arduino Software integrated development environment (IDE), which is common to all Arduino boards and running both online and offline.The board can be powered through a type-B micro-USB cable or from a 9 V battery.●In 2019, Arduino released the Arduino Nano Every, a pin-equivalent evolution of the Nano. It features a more powerful ATmega4809 processor and twice the RAM.

ALTRASONIC SENSOR
Ultrasonic sensor provides an easy method of distance measurement. This sensor is perfect for any number of applications that require you to perform measurements between moving or stationary objects. Interfacing to a microcontroller is a snap. A single I/O pin is used to trigger an ultrasonic burst (well above human hearing) and then "listen" for the echo return pulse.

A buzzer or beeper is an audio signalling device,which may be mechanical, electromechanical, or piezoelectric. Typical uses of buzzers and beepers include alarm devices, timers and confirmation of user input such as a mouse click or keystroke.
Description..
The block diagram explains us how the unit works.●The Ultrasonic Spectacles and Waist-belt for Visually Impaired and Blind people explains the interfacing section of each component with micro controller and ultrasonic sensor.●Regulated power supply is also connected to micro controller and LED’s also connected to micro controller through resistors.

Application.
It works as a navigation device for the blind people . ● This system can be used to navigate by everyone not only visually impaired under certain circumstances , like foggy mornings with low visibility. Some winter mornings are foggy, where the visibility is very low, then this system can be used. ● This system can also be used by patients suffering with various eye ailments like cataract, exophthalmia, post eye operative situations and others. ● This system can be modified into a more sophisticated version of itself by using high intensity ultrasonic waves to be used as a navigation system for geological explorations.
featur scop
It can detect the obstacle presence from a longer distance and also helps in increasing the efficiency of the system.
🦝🦝conclusion.
This device will help the blind person be more alert about the obstacles.This project is mainly for the blind people to avoid obstacles by themselves.This project provide efficient and a economical security system
