Arduino IDE 代码
/*
  Blink

  Turns 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, MEGA and ZERO
  it is attached to digital pin 13, on MKR1000 on pin 6. LED_BUILTIN is set to
  the correct LED pin independent of which board is used.
  If you want to know what pin the on-board LED is connected to on your Arduino
  model, check the Technical Specs of your board at:

// the setup function runs once when you press reset or power the board

int lightFoot=12;

void setup() {
  //初始化数字引脚LED_BUILTIN作为输出。

  pinMode(lightFoot, OUTPUT);
  Serial. begin(9600);
  //初始化串口通讯
}

// the loop function runs over and over again forever
void loop() {
  digitalWrite(lightFoot, HIGH);  // turn the LED on (HIGH is the voltage level)
  delay(2000);                      // wait for a second
  digitalWrite(lightFoot, LOW);   // turn the LED off by making the voltage LOW
  delay(1000);                      // wait for a second
}
