一个非常简单的例子是IDE附带的BlinkWithoutDelay示例程序。 本页代码使用的接线如下图所示: 没有delay的闪灯 这是来自IDE的BlinkWithoutDelay示例程序: /* Blink without Delay Turns on and off a light emitting diode (LED) connected to a digital pin, without using the delay() function. This means ...
/*Blink without Delay 无延迟闪烁 Turns on and off a light emitting diode (LED) connected to a digital pin, without using the delay() function. This means that other code can run at the same time without being interrupted by the LED code. ...
那是把pin13短接到0V,从而关闭LED灯。在LED灯开和关之间,你想要足够的时间来让人看到这个变化,所以delay()命令告诉开发板1000毫秒内什么都不做。当你用delay()命令,在这段时间里没有其他的事情发生。如果你明白这个基本例子,查看BlinkWithoutDelay的例子来学习当在做其他事时怎么制作一个延时 ...
下面的程序是从“文件”菜单中的“示例程序”中自动生成的“Blink without Delay”。 修改其中的: const long interval=1000 可以修改闪烁LED的频率。单位: ms。 下面是完整的程序。 /* Blink without Delay Turns on and off a light emitting diode (LED) connected to a digital pin...
4. BlinkWithoutDelay: 这里的bilink借鉴的是examples中的BlinkWithoutDelay.ino中的blink方法,这种写法允许在blink的同时做其它工作。比如:读取按钮的输入等。但是如果使用的是Blink.ino中的写法,在delay()的时候是不能做其它工作的。 电路图: 完整源代码: ...
2.数字量 Digital Blink Without Delay:不使用延迟 delay() 功能使LED闪烁。 Button:使用按钮控制LED。 Debounce:读取一个按钮状态,过滤噪音。...3.模拟量 Analog Analog In Out Serial:读取模拟输入引脚,输出结果,然后使用该数据调暗或增亮LED。 Analog Input:使用电位计控制LED的闪烁。...5.控制结构 Contr...
