Hello world.c

Arduino is C!

#include <stdio.h>

main ()
{
  printf("hello world\n");
}

Blink music

void setup()   {                
  pinMode(8, OUTPUT);
  for (int i=0; i<1000; i++) {
    digitalWrite(8, HIGH);
    delay(1);
    digitalWrite(8, LOW);
    delay(1);
  }
}

void loop () {}


change the argument to the delay...

for my refined control, try delayMicroseconds

void setup()   {                
  int x;
  // initialize the digital pin as an output:
  pinMode(8, OUTPUT);
  for (int i=0; i<1000; i++) {
    digitalWrite(8, HIGH);
    delayMicroseconds(250);
    digitalWrite(8, LOW);
    delayMicroseconds(250);
  }
}

tone

<source lang="c"> void setup() {

 tone(8, 500, 100);
 delay(100);
 tone(8, 600, 100);
 delay(100);
 tone(8, 700, 100);
 delay(100);
 tone(8, 800, 100);
 delay(100);
 tone(8, 900, 100);
 delay(100);
 

}

void loop() {} </source lang="c">
