早上好!最近我买了一块Arduino板,在我的房间里做了一些"灯光控制".这是我写的固件的代码:

int control = 0;
int pin = 0;

void setup()
{
  Serial.begin(9600);
  for(pin = 0; pin <= 13; pin++) pinMode(pin, OUTPUT);
}

void loop()
{
  control = Serial.read();
  if (control > 0 && control <= 13) digitalWrite(control, HIGH);
  if (control < 256 && control >= (256-13)) digitalWrite((256-control), LOW);
}

之后,我使用Python解释器的pySerial来控制引脚,一切都运行正常.这是一个解释器输出:
