EYE FOR BLIND

🔌 Wiring Diagram (Text Format):

👉 Ultrasonic Sensor (HC-SR04):

VCC → 5V on Arduino
GND → GND on Arduino
TRIG → Digital Pin 9
ECHO → Digital Pin 10

👉 Buzzer:

+ (Positive) → Digital Pin 8
– (Negative) → GND on Arduino

CODES ARE BELOW COPY AND PASTE ON ARDUINO IDE

#define trigPin 9

#define echoPin 10

#define buzzer 8

void setup() {

pinMode(trigPin, OUTPUT);

pinMode(echoPin, INPUT);

pinMode(buzzer, OUTPUT);

Serial.begin(9600);

}

void loop() {

long duration;

int distance;

// Send trigger pulse

digitalWrite(trigPin, LOW);

delayMicroseconds(2);

digitalWrite(trigPin, HIGH);

delayMicroseconds(10);

digitalWrite(trigPin, LOW);

// Read echo

duration = pulseIn(echoPin, HIGH);

distance = duration * 0.034 / 2;

Serial.print("Distance: ");

Serial.print(distance);

Serial.println(" cm");

// If object is within 100 cm (1 meter), activate buzzer

if (distance <= 100) {

digitalWrite(buzzer, HIGH);

} else {

digitalWrite(buzzer, LOW);

}

delay(200);
