Starting with a very simple program...

<source lang="c">
void setup() {
  tone(11, 220, 60);
  delay(100);
  tone(11, 440, 60);
  delay(100);
  tone(11, 880, 60);
  delay(1000);
}

void loop() {
}
</source>

How do frequencies relate to tones... See [https://en.wikipedia.org/wiki/Piano_key_frequencies Piano key frequencies]

== Incrementing 3 ways ==
All 3 are ways to add 1 to the variable x.

<source lang="c">
x = x + 1
x++;
x += 1;
</source>



== Simple counting loop (while loop) ==
Counting to 10 with a while loop...

Three main parts,
* Initializing the variable
* The "control" in the while (....) 
* Incrementing

<source lang="c">
void setup() {
  int counter = 0;
  while (counter < 10) {
    tone(11, 440, 50);
    delay(1000);
    tone(11, 220, 50);
    delay(1000);
    counter = counter + 1;
  }
}

void loop() {
  // put your main code here, to run repeatedly:
}
</source>


full text with Serial tracing
<source lang="c">
void setup() {
  // put your setup code here, to run once:
  Serial.begin(9600);
  Serial.println("hello");
  
  int counter = 0;
  Serial.print("YOUR Kounter is now ");
  Serial.println(counter);
  
  while (counter < 10) {
    tone(11, 440, 50);
    delay(1000);
    tone(11, 220, 50);
    delay(1000);

    counter = counter + 1;
    Serial.println(counter);
  }
}

void loop() {
  // put your main code here, to run repeatedly:

}
</source>

== Simple counting loop (for loop) ==
Counting to 10 with a for loop...

Three main parts,
* Initializing the variable
* The "control" in the while (....) 
* Incrementing

<source lang="c">
void setup() {
  int counter = 0;
  while (counter < 10) {
    tone(11, 440, 50);
    delay(1000);
    tone(11, 220, 50);
    delay(1000);
    counter = counter + 1;
  }
}

void loop() {
  // put your main code here, to run repeatedly:
}
</source>

== Play with NOTE NAMES ==
