how you can create a basic prototype of smart glasses for a blind person using an Arduino Uno along with ultrasonic sensors for obstacle detection and a buzzer for alerts:
*Description of Smart Glasses for Blind Individuals using Arduino Uno:*
These smart glasses are designed to assist blind individuals in navigating their surroundings safely. The Arduino Uno microcontroller is the heart of this device, coordinating inputs from ultrasonic sensors to detect obstacles and providing feedback through a buzzer.
*Components:*
1. Arduino Uno
2. Ultrasonic Sensors (HC-SR04)
3. Buzzer
*Functionality:*
*Ultrasonic Sensors* mounted on the glasses detect obstacles within a certain range.
*Arduino Uno* processes the sensor data and determines the distance of the obstacles.
If an obstacle is detected within a predefined distance, the *buzzer* emits a sound to alert the wearer.
*Arduino Code:*
Here's a simple example code for the Arduino Uno:
code

*How It Works:*
1. The Arduino initializes the ultrasonic sensor and buzzer pins.
2. In the `loop()` function:
The ultrasonic sensor sends a pulse.
The Arduino measures the duration of the pulse's return echo.
It calculates the distance based on the time taken for the echo.
If the distance is less than or equal to the `safeDistance`, the buzzer sounds an alert.
3. The process continues in a loop, constantly checking for obstacles.
*Note:*
Adjust the `safeDistance` value according to the desired proximity for obstacle detection.
The buzzer will emit a sound when an obstacle is detected within the specified range.
This is a basic example to get started. For a more sophisticated system, you can add more sensors for broader coverage, integrate Bluetooth for connectivity to a smartphone app, or include voice feedback using a speech synthesis module.
