硬體配置
參考範例程式 "Arduino - LED"

程式
-----------------------------------------

	const byte LED = 13;

	void setup() {

	// init serial port
	Serial.begin(9600);
	Serial.print("Hello, LED pin is: ");
	Serial.println(LED);

	// init LED
	pinMode(LED, OUTPUT);
	}

	void loop() {
	char val;

	if ( Serial.available() ) {
	val = Serial.read();
	if ( val == '1' ) {
	digitalWrite(LED, HIGH);
	Serial.println("LED ON");
	} else if ( val == '0' ) {
	digitalWrite(LED, LOW);
	Serial.println("LED OFF");
	} else {
	Serial.print("LED no change, input is: ");
	Serial.println(val);
	}
	}
	}

開啓 Tools -> Serial Monitor

結果 : 送出 "1", LED 會亮; 送出 "0", LED 會熄滅
