 Open your Arduino software and carefully type in the code:
void setup()
{
Serial.begin(9600);
Serial.print("Hello!");
}
void loop()
{
//Add code that repeats automatically here.
}
 Be sure you have capitalized “Serial” both times, or the sketch won’t work.
 Also, notice in the figure that the sketch uses parentheses
() and curly braces {}.
Be sure to use the right ones in the right places!
 Click the Verify button to make sure your code doesn’t have any typing errors.
 Look for the “Binary sketch size” text in the message pane.
 If it’s there, your code compiled and is ready to load to the Arduino.
 If there’s a list of errors instead, it’s trying to tell you it can’t compile your code.
So, find the typing mistake and fix it!
 Click the arrow button to upload the sketch and run it on the Arduino. The status
line under your code will display “Compiling sketch…,” “Uploading…,” and then
“Done uploading.”
 After the sketch is done uploading, click the Serial Monitor button.
 If the Hello message doesn’t display as soon as the Serial Monitor window opens,
check for the “9600 baud” setting in the lower right corner of the monitor.
 Use File → Save to save your sketch. Give it the name HelloMessage.
If you’ve successfully run the code and verified the output in the Serial Terminal, you are
ready to see How the Hello Sketch Code Works on page 20.
