### Code

In this example, the buzzer will play a 1KHz tone for 1 second, then silence for 1 second as long as it's plugged in.

```cpp
// Buzzer is connected to pin 9 on the Arduino circuit board
int buzzer = 9;

void setup() {
  // Establish the component connection and its type (output/input)
  pinMode(buzzer, OUTPUT);
}

void loop() {
  tone(buzzer, 1000);   // Plays 1KHz tone
  delay(1000);          // Plays this tone for 1 second
  noTone(buzzer);       // Plays no tone
  delay(1000);          // Plays this tone for 1 second
}
```

### Code

This code will make the LED light up for 1 second and go off for 1 second until it is unplugged.

```cpp
// LED is connected to pin 9 on the Arduino circuit board
int LED = 9;

void setup() {
  // Establish the component connection and its type (output/input)
  pinMode(LED, OUTPUT);
}

void loop() {
  digitalWrite(LED, HIGH);  // Turn light on
  delay(1000);              // Wait 1 second
  digitalWrite(LED, LOW);   // Turn light off
  delay(1000);              // Wait 1 second
}
```

## Multiple LEDs

This example shows using and controlling two separate LEDs as an example of multiple output components.

### Code

This code will alternate the lights lighting for 1 second each with a second of darkness in between until the Arduino is unplugged.

```cpp
// 1st LED is connected to pin 10 on the Arduino circuit board
int LED = 10;

// 2nd LED is connected to pin 9 on the Arduino circuit board
int LED2 = 9;

void setup() {
  // Establish the component connection and its type (output/input)
  pinMode(LED, OUTPUT);
  pinMode(LED2, OUTPUT);
}

void loop() {
  digitalWrite(LED, HIGH);  // Turn light on
  delay(1000);              // Wait 1 second
  digitalWrite(LED, LOW);   // Turn light off
  delay(1000);              // Wait 1 second
  digitalWrite(LED2, HIGH);  // Turn light on
  delay(1000);              // Wait 1 second
  digitalWrite(LED2, LOW);   // Turn light off
  delay(1000);              // Wait 1 second
}
```

## RGB LED

This is a special LED that you can use 0-255 color values to get any color of the RGB rainbow.

### Diagram

Note: This diagram is for a Cathode RGB LED where the 2nd connector is the ground (negative) connection.

## Code

This example turns the light cyan using the "simple" way (setting each color with a line of code).

```cpp
// Red pin is connected to pin 11 on the Arduino circuit board
int red = 11;

// Green pin is connected to pin 10 on the Arduino circuit board
int green = 10;

// Blue pin is connected to pin 9 on the Arduino circuit board
int blue = 9;

void setup() {
  // Establish the component connection and its type (output/input)
  pinMode(red, OUTPUT);
  pinMode(green, OUTPUT);
  pinMode(blue, OUTPUT);
}

void loop() {
  // Example of Cyan (0, 255, 255)
  analogWrite(red, 0);
  analogWrite(green, 255);
  analogWrite(blue, 255);
  delay(1000);
} 
```

This example shows the same thing, but using a custom function, making color changes take fewer lines of code:

```cpp
// Red pin is connected to pin 11 on the Arduino circuit board
int red = 11;

// Green pin is connected to pin 10 on the Arduino circuit board
int green = 10;

// Blue pin is connected to pin 9 on the Arduino circuit board
int blue = 9;

void setup() {
  // Establish the component connection and its type (output/input)
  pinMode(red, OUTPUT);
  pinMode(green, OUTPUT);
  pinMode(blue, OUTPUT);
}

void loop() {
  // Example of Cyan (0, 255, 255)
  RGB_Color(0, 255, 255);
  delay(1000);
} 

void RGB_Color(int redValue, int greenValue, int blueValue) {
  analogWrite(red, redValue);
  analogWrite(green, greenValue);
  analogWrite(blue, blueValue);
}
```
