2、Blink.ino中用到的几个函数: ① pinMode(pin,mode) : 将指定的引脚配置为输入或输出 - pin : 所需要设置的引脚号 - mode : INPUT/OUTPUT(pinMode也可以是INPUT_PULLUP,使用引脚内置的上拉电阻) pinMode(LED_BUILTIN, OUTPUT); ② digitalWrite(pin,HIGH/LOW) : 数字引脚输出,HIGH表示高电平(5v),LO...
digitalWrite(led, HIGH); // turn the LED on (HIGH is the voltage level) delay(1000); // wait for a second digitalWrite(led, LOW); // turn the LED off by making the voltage LOW delay(1000); // wait for a second } 复制代码 代码开头: /* Blink Turns on an LED on for one seco...
const long interval = 1000; // interval at which to blink (milliseconds)void loop() { // 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 ...
After you build the circuit plug your Arduino board into your computer, start the Arduino Software (IDE) and enter the code below. You may also load it from the menu File/Examples/01.Basics/Blink . The first thing you do is to initialize LED_BUILTIN pin as an output pin with the line...

为什么arduino的blink中pinmode是LED_BUILTIN而不是13号引脚。是因为LED_BUILTIN函数主要用来点亮Arduino主板内置的LED灯的，Arduino有不同的板型，主板内置的LED灯的引脚也有所不同，不一定都是13引脚。用LED_BUILTIN函数不管主板内置的LED灯是哪个引脚都回被点燃亮。

Make the blink LED exampleNow that you have the circuit and the code to setup the LED, let’s do something a bit more interesting.Let’s make the LED blink, which means that we are going to:Power on the LED, wait, Power off the LED, wait, Go back to 1....
