所需硬體
- Arduino或者Genuino開發板
- LED
- 220歐電阻
電路連接方式
搭建電路時，將電阻的一端連接到Arduino的13引腳。將LED的長腿的一端（正極引腳，稱為陽極）連接到電阻的另一端。將LED的短腿（負極引腳，稱為陰極）連接到Arduino的GND。
代碼
/*
Blink
Turns on an LED on for one second, then off for one second, repeatedly.
Most Arduinos have an on-board LED you can control. On the Uno and
Leonardo, it is attached to digital pin 13. If you're unsure what
pin the on-board LED is connected to on your Arduino model, check
the documentation at http://www.arduino.cc
This example code is in the public domain.

// the setup function runs once when you press reset or power the board
void setup() {
// initialize digital pin 13 as an output.
pinMode(13, OUTPUT);
}
// the loop function runs over and over again forever
void loop() {
digitalWrite(13, HIGH); // turn the LED on (HIGH is the voltage level)
delay(1000); // wait for a second
digitalWrite(13, LOW); // turn the LED off by making the voltage LOW
delay(1000); // wait for a second
}
