Arduino按键控制LED灯实验二按下按键LED灯亮，再按按键LED灯灭int buttonPin=2;int ledPin=13;boolean ledState=false;void setup(){ pinMode(buttonPin,INPUT_PULLUP); pinMode(ledPin,OUTPUT);}void loop(){ while(dig...

Arduino按键点亮LED实验用了两个电阻，一个为220Ω与LED灯串联，防止电流过大烧毁LED,为限流电阻。另一个电阻为10kΩ与按键并联，为下拉电阻。当按键未按下时，2号引脚悬空，此时用digitalRead()函数读取2号引脚状态。可直接选择02.Digital->Button/* Button Turns on and off a light emitting di...

Arduino流水灯实验所需材料：Arduino UNO,面包板，LED灯，220Ω电阻。从引脚2到引脚7来回逐个点亮LED。void setup() { for(int i=2;i<8;i++) pinMode(i,OUTPUT); // put your setup code here, to run once:}void loop() { for(int i=...

Arduino中Hello world----Blink在Basics->Blink菜单可打开示例程序Arduino控制板中13号引脚连接标“L”的LED灯，Upload后Arduino控制器上标有TX,RX的两个LED灯快速闪烁，下载完毕后标有L的LED灯按程序设定闪烁。int led = 13;void setup() { pinMode(led,OUTPUT); //...
