Question

What command do we add to our code to initialize the debug monitor space in the
Arduino IDE? Be complete in your answer.

Answer 1

To initialize the debug monitor space in the Arduino IDE, you typically want to start using the Serial communication features. The specific command to initialize the Serial communication is as follows:

```cpp
void setup() {
Serial.begin(9600); // Initialize the Serial communication at a baud rate of 9600 bps
}
```

Here's a complete example that includes the full structure of an Arduino sketch:

```cpp
void setup() {
Serial.begin(9600); // Start the Serial communication at 9600 baud rate
}

void loop() {
Serial.println("Hello, debug monitor!"); // Print a message to the debug monitor
delay(1000); // Wait for a second
}
```

### Explanation:
1. **`Serial.begin(9600);`**: This initializes the Serial port at a baud rate of 9600 bits per second. You can change the baud rate to match the setting you choose in your Arduino IDE's Serial Monitor.
2. **`Serial.println("Hello, debug monitor!");`**: This line sends the string "Hello, debug monitor!" from the Arduino board to the Serial Monitor, allowing you to view it.
3. **`delay(1000);`**: This introduces a delay of 1 second (1000 milliseconds) in the loop, ensuring that the message is printed once every second.

### Using the Serial Monitor:
To view the output sent by the Arduino sketch, open the Serial Monitor in the Arduino IDE by clicking on the magnifying glass icon in the top right corner or using the shortcut `Ctrl + Shift + M` (Windows) or `Cmd + Shift + M` (Mac). Make sure the baud rate in the Serial Monitor matches the baud rate specified in your code (in this case, 9600).
