First, take Four jumper wires and put them in ultrasonic sensors.

VCC - 5v

Trig - 13

Echo - 12

Gnd - Ground

Buzzer positive wire to connect Arduino pin 7

Buzzer negative wire to Arduino Ground

Battery positive wire to connect Arduino pin V1n

Battery negative wire to Arduino Ground.

Arduino Uno, Battery, ultrasonic sensor and switch added to the helmet.

Now its time for uploading the sketch.The sketch for the Arduino is given below, copy this into your Arduino IDE, then upload into your Arduino

#define trigPin 13

#define echoPin 12

#define motor 7

#define buzzer 6void setup(){pinMode(trigPin, OUTPUT);pinMode(echoPin, INPUT);pinMode(motor, OUTPUT);pinMode(buzzer,OUTPUT);}void loop(){long duration, distance;digitalWrite(trigPin, LOW); delayMicroseconds(2); digitalWrite(trigPin, HIGH);delayMicroseconds(10); digitalWrite(trigPin, LOW);duration = pulseIn(echoPin, HIGH);distance = (duration/2) / 29.1;if (distance < 70)// This is where checking the distanceyou can change the value{ digitalWrite(motor,HIGH); // When the the distance below 100cmdigitalWrite(buzzer,HIGH);} else{digitalWrite(motor,LOW);// when greater than 100cmdigitalWrite(buzzer,LOW); } delay(500);}
