Aim
The aim of the project is to alert the blind persons if there is an object in their pathway.
Problem statement
In most cases the visually impaired people have a problem they cannot navigate freely in an environment. The solution is to design an assistive wearable cap for the blind or visually impaired persons.
Material used
Input: Ultrasonic Sensor
Brain: TinkerSpace Brain Board
Output: Buzzer
Battery: Lithium-ion rechargeable battery
Component description
ULTYRASONIC SENSOR
The function of IR Proximity Sensor is to detect objects and send the signal to the Brain unit (TinkerSpace board).
BUZZER
The function of the Buzzer is to produce sound
TinkerSpace Brain Board
TinkerSpace board acts as brain of this project, its function is to monitor Ultrasonic Sensor and control the Buzzer
Battery
5V Lithium-Ion battery is used to power-up this project
Working description
WORKING DESCRIPTION:
Case – 1: When an object is detected near the blind person, the ultrasonic sensor (input) measures the distance and if it is less than 20cm, it sends the distance measurement to the TinkerSpace brain board (brain). The brain board turns ON the buzzer (output).
Case – 2: When no object is detected near 20cm, the brain board turns OFF the buzzer.
Object is present within 20cm —> Buzzer ON
Object is not present within 20cm —> Buzzer OFF
Circuit Design (DesignSpace)
Step 1: Open TCode App -> Create New project -> Open DesignSpace
Step 2: Connect the Ultrasonic sensor to INPUT 3 of the Brain board.
Step 3: Connect Buzzer Output 1 of the Brain Board.
Step 4: Connect supply and test project.
