pinMode(2,INPUT_PULLUP); 把作为LED灯的pin13初始化为输出引脚: pinMode(13, OUTPUT); 现在初始化完成了,移入你代码的主循环里。当按钮被按下,5V电压会流过你的电路,而当它没有被按下,这个输入引脚就会链接到通过10k ohm电阻连接到地。这是数字输入,意味着开关只有开(1,或者高电平)和关(0,或者低电平...
pinMode(led, OUTPUT); 1. pinMode()函数,官方解释: Configures the specified pin to be have either as an input or an output . See the Digital Pins page for details on the functionality of the pins. 1. 2. 简单来说即设置引脚的模式为输入或者输出。函数内部被花括号括起来的部分将会被依次执行...
