Buzzer Sonar
A Sonar Radar that uses HC-06 to measure the distance of the object infront of it, and then beep faster as the object comes closer. Component List:- 1 x Arduino Uno R3
- Jumper Wires
- 1 x Buzzer
- 1 x HC-06
Wiring Guide:
- Connect the HC-SR04 Ultrasonic Sensor:
- Connect the VCC pin of the sensor to the 5V pin on the Arduino (or breadboard).
- Connect the GND pin of the sensor to the GND pin on the Arduino (or breadboard).
- Connect the TRIG pin of the sensor to digital pin 9 on the Arduino.
- Connect the ECHO pin of the sensor to digital pin 10 on the Arduino.
- Connect the Buzzer:
- Connect the positive (longer) leg of the buzzer to digital pin 8 on the Arduino.
- Connect the negative (shorter) leg of the buzzer to the GND pin on the Arduino (or breadboard).
CODE:
#define TRIG_PIN 9
#define ECHO_PIN 10
#define BUZZER_PIN 8
void setup() {
Serial.begin(9600);
pinMode(TRIG_PIN, OUTPUT);
pinMode(ECHO_PIN, INPUT);
pinMode(BUZZER_PIN, OUTPUT);
}
void loop() {
long duration, distance;
// Clear the trigger pin
digitalWrite(TRIG_PIN, LOW);
delayMicroseconds(2);
// Send a 10 microsecond pulse to the trigger pin
digitalWrite(TRIG_PIN, HIGH);
delayMicroseconds(10);
digitalWrite(TRIG_PIN, LOW);
// Measure the time taken for the pulse to return
duration = pulseIn(ECHO_PIN, HIGH);
// Calculate the distance in centimeters
distance = (duration / 2) / 29.1;
// Print the distance to the Serial Monitor
Serial.print("Distance: ");
Serial.print(distance);
Serial.println(" cm");
// Set a longer delay if distance is above 60
int beepDelay = (distance > 60) ? 1000 : map(distance, 2, 60, 50, 500);
// Set a shorter beep duration
int beepDuration = 50;
// Control the buzzer based on the distance
tone(BUZZER_PIN, 1000, beepDuration); // Constant frequency for the example
delay(beepDuration);
// Stop the buzzer after the beep duration
noTone(BUZZER_PIN);
// Add an additional delay for distances above 60
if (distance > 60) {
delay(1000); // 1-second delay between beeps
} else {
delay(beepDelay); // Delay between beeps
}
}
