// here is where you'd put code that needs to be running all the time. // check to see if it's time to blink the LED; that is, if the // difference between the current time and last time you blinked // the LED is bigger than the interval at which you want to // blink th...
/*ButtonTurns on and off a light emitting diode(LED) connected to digital pin 13,when pressing a pushbutton attached to pin 2.The circuit:- LED attached from pin 13 to ground through 220 ohm resistor- pushbutton attached to pin 2 from +5V- 10K resistor attached to pin 2 from ground- ...
// set the LED with the ledState of the variable: 设置LED 的状态为 ledState 变量的值 digitalWrite(ledPin, ledState); } } 2、非延迟闪烁 - Blink Without Delay Sometimes you need to do two things at once. For example you might want to blink an LED while reading a button press. In t...
In this Arduino tutorial I will show you how to turn an LED on and off with a push button. In fact, we’ll do 2 slightly different applications.First, we will power on the LED when the button is pressed, and power off the LED when the button is not pressed....

运行此node.js 程序后,即可在终端窗口中测试上文提到的led 对象方法,回力例如led.on() 将点亮LED。 接着输入led.blink(500) 或led.strobe(500),LED 将以500ms 时间间隔闪烁(默认间隔时间为100ms),直到输入led.stop() 为止。测试完毕后,按两次“Ctrl+C”快捷键退出程序。

The second code example is a little more interesting as it switches that pin on and off every 1,000 milliseconds (1 second). The orange LED will blink at one-second intervals…or will it? voidsetup() {//The following code will be executed once when your Arduino turns on.pinMode(13, ...
