Step 5: Write Your First Sketch

“Sketch” is the term used in the Arduino IDE to refer to your code. It consists of two main functions: setup() and loop(). The setup() function runs once when you start your board, while the loop() function runs repeatedly. Follow these steps to write a simple “Hello World” sketch:

  1. Create a New Sketch: Click on “File” in the top menu and select “New” to open a new sketch window.

  2. Enter Your Code: Copy and paste the following code into the new sketch window:

    void setup() {
 Serial.begin(9600); // Start the serial communication
}

void loop() {
 Serial.println("Hello, World!"); // Print "Hello, World!"
 delay(1000); // Wait for a second
}

  3. Explanation of the Code:

    • Serial.begin(9600); initializes serial communication at a baud rate of 9600.
    • Serial.println("Hello, World!"); sends the message "Hello, World!" to the serial monitor.
    • delay(1000); pauses the loop for one second.

Step 6: Upload the Sketch to Your Arduino

  1. Connect to the Board: Ensure your Arduino board is still connected to your computer via USB.

  2. Verify the Sketch: Click the checkmark icon in the upper left corner of the Arduino IDE to compile the code. This will catch any syntax errors.

  3. Upload the Code: Once verified, click the right arrow icon next to the checkmark. The IDE will begin uploading the code to the connected Arduino board. Watch for messages in the console window at the bottom of the IDE.

  4. Open Serial Monitor: After uploading, open the Serial Monitor by clicking on the magnifying glass icon at the top right of the IDE or selecting "Tools" > "Serial Monitor". Set the baud rate to 9600 to match what you defined in your sketch.

  5. View Output: You should see "Hello, World!" being printed to the Serial Monitor every second.
