那让a代表引脚1的程序怎么写呢?

比如 arduino 自带的例子中有

// constants won't change. Used here to
// set pin numbers:
const int ledPin = 13; // the number of the LED pin

// if the LED is off turn it on and vice-versa:
if (ledState == LOW)
ledState = HIGH;
else
ledState = LOW;

// set the LED with the ledState of the variable:
digitalWrite(ledPin, ledState);
