The Arduino blink LED circuit is a simple circuit that works great for starting to learn Arduino. Both the code and the connections are straightforward so that you can understand it with little to no background. In this quickstart guide, you’ll learn how to connect an LED to an Arduino b...
pinMode(ledPin, OUTPUT); } 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 you blinked // the LED is bigger than th...
const long interval = 1000; // interval at which to blink (milliseconds) 闪烁的时间间隔(毫秒) void setup() { // set the digital pin as output: 设置数字针脚为输出 pinMode(ledPin, OUTPUT); } (4)循环函数 void loop() { // here is where you'd put code that needs to be running all...

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. ...
Blink - turn an LED on and off Button State Change - counting the number of button pushes 3、后记 (1)fritzing 电路接线图 今天用 fritzing 绘制的图,上篇多了一个 LED。 不画LED 也可以,使用板载 LED,就是 Arduino 板载上标记为 L 位置的 LED。 白色的 LED 看不太清楚,换了一个红色 LED: (2...
