ULTRASONIC RADAR PROJECT FOR THE VISUALLY IMPAIRED
or
THIRD EYE FOR BLIND
The main purpose of my project is to make the lives of blind people or even the visually impaired people easier, with the help of ultrasonic distance sensor, to detect objects in front of the person and to prevent them from hitting objects by giving an audible warning and vibrations.
cane sticks can only provide limited assistance, what if we could provide third eye to the visually impaired.
I make this project for my grandmother's sister, she can't see clearly, this project will help her a lot by preventing her from hitting objects when she is alone, she is my inspiration.
i also searched google and youtube for more ideas about it.
here is some links of videos of similar projects:

2- Describe the project idea and general features. How would it work?
-The main project idea:
The ultrasonic radar project for the visually impaired is designed to facilitate the lives of visually impaired people and to provide access to this device in the cheapest way,
by making use of ultrasonic waves to detect nearby obstacles and to notify the user through beeps of a buzzer, the number of beeps increases as we get closer to any object and through vibrations from the micro vibration motor that makes vibrations with the sound also they can choose if they want the project to play on sound mode or vibration mode through the switch.
i make it to look like a wristwatch so it will be easy to use.
-How it would work:
Ultrasonic sensor was used as sensor and Arduino uno was used as microcontroller. The programming part of the project has been completed with the Arduino IDE, which acts as a code editor and compiler, and also performs the process of uploading the compiled program to the card.
The distance information obtained with the help of sensors is given to Arduino.
Arduino outputs are connected with electronic circuit. Arduino, which made the appropriate decision according to the distance information, sensed the objects with the ultrasonic distance sensor and gave an audible warning with the buzzer speaker and vibrations through the micro vibration motor
-Advantages of the project:
this ultrasonic radar is more comfortable to wear and carry than other visually impaired assist systems.
unlike other other products produced for visually impaired it can be worn on the wrist like a wrist watch to allow easy movement so when the person using this product doesn't have to leave or remove the product when he wants to deal with something else.
small.
low production cost.
low production time.
work with low consumption.
can work outdoor and indoor.
if you have a problem with the sound you can be able to change the mode to the vibration mode, to make it silent by a switch.
we can wear it like a wrist watch

4- Describe the Technical Modules that your project consists of
Construction Parts
i will use 3D printing to make the box that contains the internal parts.
Input (Sensing and/or User)
sensing input:
HC-SR04 Ultrasonic sensor to sense the objects when it get closer.
tactile input:
on/off switch to run the project
press switch to change the mode from silent(vibration) to sound and from sound to silent
Action
The buzzer makes sound(beeps) and the LED emits light
,as objects get closer the the number of beeps increase also the amount of light increases.
micro vibration motor that makes vibrations with the sound also when the objects get closer the number of vibrations increase .
you can choose between sound mode and vibration mode through a switch.
Brain
AN arduino NANO board will be used to take inputs from the ultrasonic sensor and generate actions through the buzzer and the micro vibration motor.
Power Management
9V Battery

to create the prototype i cut the cardboard, making four sides , top and bottom.
6- Categorize your project’s User Features into: Minimum, Complete, and Nice-to-have features. List the required action and input components per feature.
6- Categorize your project’s User Features into: Minimum, Complete, and Nice-to-have features. List the required action and input components per feature.
Minimum Features: are the least amount of features that would demonstrate the coverage of all the technical modules and their complete integration
Complete Features: are the set of features that will complete your original project objective and vision
Nice-to-have Features: are the extra set of features that will make the project cooler, yet they need extra time, effort, and/or resources to finish
Minimum User Features
The micro vibration motor makes vibrations, when the objects get closer the number of vibrations increase .
Action: micro vibration motor
Sensing: Ultrasonic sensor
User Input: on/off switch
Buzzer makes sound(beep) when objects get closer and the number of beeps increases as we get closer to any object.
Action: buzzer
Sensing: Ultrasonic sensor
User Input: on/off switch
Complete User Features
using the slide switch to change the mode from vibration mode to sound mode.
or from the sound mode to the vibration mode if the user need less noise.
Action: micro vibration moto and buzzer
Sensing: Ultrasonic sensor
User Input: slide switch
Nice-to-have User Features
The buzzer will make lil sound and the vibration motor will vibrate when you switch on the power to warn the user that the project is on
Action: micro vibration moto and buzzer
