Incompatible with Arduino built-in tone( ) function

Issue #58 resolved
Former user created an issue

Error result during compilation of a simple sketch using this lib and tone()

Arduino: 1.8.13 (Windows 10), Board: "Arduino Uno"
Tone.cpp.o (symbol from plugin): In function `timer0_pin_port':
(.text+0x0): multiple definition of `__vector_7'
libraries\NewPing\NewPing.cpp.o (symbol from plugin):(.text+0x0): first defined here
collect2.exe: error: ld returned 1 exit status
exit status 1

Here's a sample sketch

#include <NewPing.h>
#define TRIGGER_PIN  8  // Arduino pin tied to trigger pin on the ultrasonic sensor.
#define ECHO_PIN     9  // Arduino pin tied to echo pin on the ultrasonic sensor.
#define MAX_DISTANCE 300 // Maximum distance we want to ping for (in centimeters). Maximum sensor distance is rated at 400-500cm.
#define BUZZER 5

NewPing sonar(TRIGGER_PIN, ECHO_PIN, MAX_DISTANCE); // NewPing setup of pins and maximum distance.

void setup() {
  Serial.begin(115200); // Open serial monitor at 115200 baud to see ping results.
}

void loop() {
  Serial.print(sonar.ping_cm());
  tone(BUZZER, 500);
  delay(5000);
  noTone(BUZZER);
}
