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.
Code: [Select]
int speaker = 4;

void setup() {
 pinMode(speaker, OUTPUT);

void loop() {
 for (int i=0; i<30; i++) {
   digitalWrite(speaker, HIGH);
   digitalWrite(speaker, LOW);

Here example sound: http://www.youtube.com/watch?v=eQVaLWMPXHk

THX in advance!



Frequency of beep, length of beep, and time between beeps.  It's then just a loop.

My hardware: Arduino, Teensy 2.0, Teensy 3.2 & custom ATmega328
My libraries: NewPing, LCDBitmap, toneAC, toneAC2, NewTone, TimerFreeTone
