Story

Introduction

This is a new innovative project. This project is about the efficiency of the IR sensors. It will not give us rough signals to buzzer if the object crosses the sensor. It tracks the object, if the object is moved within 100-500 micro seconds, the buzzer will not give us signals. But if it is a stable object, it gives a signal. If the blind is also a deaf, nothing to worry, there is a vibration actuator to make vibrations and give signals. LETS GO INTO THE PROJECT.

Circuits

Connect the buzzer to digital pin 13

Connect the IR signal pin to the analog pin 0

Make a switch for buzzer

Make a switch for the power.

Connect the Bluetooth module as default.

Guide (how to connect the HC-05 to Arduino): https://create.arduino.cc/projecthub/user206876468/arduino-bluetooth-basic-tutorial-d8b737?f=1

Download the Given app in your Android Phone.

Go for it.

// Made by, Chandru
const int signalPin= 0;// Connect the IR Signal pin to Analog 0 Pin (A0)
const int buzzPin= 13; //Connect Buzzer to Digital Pin 13
int signal;

void setup() {
Serial.begin(9600); 
pinMode(signalPin, INPUT); 
pinMode(buzzPin, OUTPUT); 
}

void loop() {
signal= analogRead(signalPin); 
Serial.println(signal); 
delay(100); 

if(signal > 100){ #  //Intensity can be changed from 100 to 750, But Sensor will not get its Efficiency
digitalWrite(buzzPin, HIGH);
}
else{
digitalWrite(buzzPin, LOW);
}
}
//Thanks for Uploading to your Arduino Board.....👁️Help Blinds👁️
