Story

This Project has kind of steps. I made it as a training project in my Bachelor's.

Here's the steps of the project:

STEP 1:

DOWNLOAD AND INSTALL ARDUINO IDE FROM THE PORTAL.

STEP 2: HARDWARE COMPONENTS AND MATERIALS

>>Arduino board

>>Breadboard

>>LED Light

>>Piezo speaker(BUZZER)

>>Ultrasonic sensor

>>Jumper wires

>>Resistors

STEP 3: BUILD UP THE HARDWARE

>>Add LED to the baking board. Connect the short LED leg to the Ground, the long LED leg to pin 7 with the jumping wires and the opposing elements shown in the drawing.

>>Secondly, Add the BUZZER to the breadboard and Connect the short leg of the BUZZER to the Ground, long leg to pin 9 with jumper wires and resistors.

>>In addition, the ultrasonic sensor to the breadboard. There are 4 pins in the ultrasonic sensor. They are Vcc (5V power supply), Trig (Trigger), Echo, Gnd (Groud). Connect Vcc to 5V power supply, Gnd to Ground, Echo to pin 13, Trigger to pin 11 with jumper wires and resistors.

STEP 4: DOWNLOAD THE PROJECT AND RUN IT.

Code

Buzzer CODE

int ledPIN = 7;
int speakerPIN = 9;
int trigPIN = 13;
int echoPIN = 11;
boolean buttonOn = false;
void setup() {
  // put your setup code here, to run once:
  pinMode(ledPIN, OUTPUT);
  pinMode(echoPIN, INPUT);
  pinMode(trigPIN, OUTPUT);
  Serial.begin(9600);
}

void loop() {

  long duration, distance;
  digitalWrite(trigPIN,HIGH);
  delayMicroseconds(1000);
  digitalWrite(trigPIN,LOW);
  duration = pulseIn(echoPIN,HIGH);
  distance = (duration/2)/29.1;
  Serial.print(distance);
  Serial.println("CM");
  delay(10);
 
  if (distance < 10) {
    digitalWrite(ledPIN, HIGH);
    tone(speakerPIN,1000);
  }
  else {
    digitalWrite(ledPIN, LOW);
    noTone(speakerPIN);
  }
}
