I want to make a beep sound with arduino that sounds like the heart monitors at hospitals. I have this code but i dont know what i need to change to make it sound like that.
int speaker = 4;
void setup() {
pinMode(speaker, OUTPUT);
}
void loop() {
for (int i=0; i<30; i++) {
digitalWrite(speaker, HIGH);
delayMicroseconds(1000);
digitalWrite(speaker, LOW);
delayMicroseconds(1000);
}
delay(1800);
}
Here example sound: - YouTube
THX in advance!
