Turn on the LED when button is pressed, turn it off otherwise What we want to achieve is simple: when the button is not pressed, the LED is off. And when we press the button the LED should be on. The code #define LED_PIN 8 #define BUTTON_PIN 7 voidsetup(){ pinMode(LED_PIN, ...

(看图片)在右边,应该打开了Simulation View。您可以通过在右下方的模拟视图中单击单词 button 来模拟按钮按下事件。活动状态应从“熄灭”更改为“点亮”。五秒钟后,或单击时间事件 Light_On_timer_event_0 后,活动状态将更改回 Light Off 。太棒了!现在,让我们检查一下如何在Arduino上使用它。
LED\ LED.ino 二、主文件代码框架规范 每一个Arduino程序(Sketch)都有1个主文件,后缀为.ino,它是程序的setup 函数和 loop函数所在的文件。 代码框架如下: void setup() { // put your setup code here, to run once: //初始化操作代码放在setup函数中,他们将在程序启动的第一步得到执行 并只执行一次 ...
F("KEY2_LONG_PRESS ,AirLink mode")); digitalWrite(ledPin, HIGH); // sets the LED on myGizwits.setBindMode(WIFI_AIRLINK_MODE); //AirLink mode break; default: break; } } void setup() {// put your setup code here, to run once: Serial.begin(9600); pinMode(ledPin, OUTPUT); ...

就让我们点亮第一颗LED灯~! 打开Raduino软件,按下图路径打开一个小程序。 这段程序非常简单: /* Blink Turns an LED on for one second, then off for one second, repeatedly. Most Arduinos have an on-board LED you can control. On the UNO, MEGA and ZERO it is attached to digital pin 13, ...
