What are some examples of using the Arduino Serial Monitor?

The Arduino Serial Monitor is a tool that allows you to communicate with your Arduino board. You can use it to send and receive data, debug your code, and monitor sensor readings. For example, you can send commands to control an LED or read temperature data from a sensor.

Can you give me a specific code example?

Sure! Here's a simple example:

void setup() {
  Serial.begin(9600);
}

void loop() {
  Serial.println("Hello, Arduino!");
  delay(1000);
}

This code sends "Hello, Arduino!" to the Serial Monitor every second.

How do I open the Serial Monitor?

To open the Serial Monitor, go to the Arduino IDE and click on the magnifying glass icon in the top right corner or press Ctrl + Shift + M.

What baud rate should I use?

The baud rate should match the one set in your code. Common rates are 9600, 115200, and 57600. Just ensure both the code and Serial Monitor are set to the same rate.
