Arduino – Turn LED ON and OFF With ButtonIn 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 ...
the correct LED pin independent of which board is used. */ void setup() { pinMode(LED_BUILTIN, OUTPUT); } void loop() { digitalWrite(LED_BUILTIN, HIGH); // turn the LED on delay(1000); // wait for a second digitalWrite(LED_BUILTIN, LOW); // turn the LED off delay(1000); ...

模拟,您可以看到 arduino nano 上的每个引脚如何能够单独控制我们立方体上的 LED。 使用Arduino Nano设计和构建4×4×4 Led Cube 检查所有 64 个 LED,确保它们使用小纽扣电池工作。 在我们开始组装 LED 立方体并进行任何焊接之前,最好确保 LED 正常工作。我们的 LED 需要 3.3 ...
2. TWO EV3 Large Motors. (Need 2 motors to demonstrate the robot's turn left and turn right functions) 2. 两只 EV3 大马达(需要两只去演示机器人的左拐和右拐功能) 3. ONE Bricktronics Motor Driver, for more information, you can find it here: ...
pinMode(led, OUTPUT); } //the loop routine runs over and over again forever: void loop(){ 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 ...
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 second, then off for one second, repeatedly. This example code is in the public domain. ...
