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. And then we’ll mo...
// The setup function that runs one time at startupvoidsetup() {pinMode(13, OUTPUT);// Initialize digital pin 13 as an output.}// The main loop that continues forevervoidloop() {digitalWrite(13, HIGH);// turn the LED on (HIGH is the voltage level)delay(1000);// wait for a seco...
我们将所有收到的命令保存在变量“Value”中 如果值为“所有 LED 打开”,则两个 LED 都打开,像这样,我们已经编码了其他语音命令来打开或关闭单个 LED。查看本文后面的完整工作和演示视频。 if (bluetooth.available()) { value = bluetooth.readString(); if (value == "all LED turn on"){ digitalWrite(2,...
void loop() { digitalWrite(13, HIGH); // turn the LED on (HIGH is the voltage level) delay(2000); // wait for a second digitalWrite(13, LOW); // turn the LED off by making the voltage LOW delay(1000); // wait for a second } 5、IDE设置 (串口选择、开发板型号选择、编译器选择...
在这种情况下,那里只有一个命令,正如注释状态告诉Arduino开发板,我们将使用LED引脚作为输出。具有“循环”功能的草图也是强制性的。 与只能运行一次的“设置”功能不同,复位后,“循环”功能将在完成其命令后立即重新启动。 void loop() { digitalWrite(led, HIGH); // turn the LED on (HIGH is the voltage ...
当用户单击 TURN ON LED 超链接时，他/她将被重定向到 URL \?LEDON，这将点亮LED。client.println(...
在本例中,只有一个命令,正如注释所述,它告诉Arduino板我们将使用LED pin作为输出。 程序必须有一个“循环”函数。与只运行一次的“setup”函数不同,在复位之后,“loop”函数将在运行完命令后立即重新启动。 void loop() { digitalWrite(led, HIGH); // turn the LED on (HIGH is the voltage level) ...
digitalWrite(13, HIGH); // turn the LED on (HIGH is the voltage level) delay(1000); // wait for a second digitalWrite(13, LOW); // turn the LED off by making the voltage LOW delay(1000); // wait for a second } 1. 2. ...
