2_LED闪烁

#define LED 5

void setup() {
  // put your setup code here, to run once:
  pinMode(LED, OUTPUT);
}

void loop() {
  // put your main code here, to run repeatedly:
  digitalWrite(LED,HIGH); //高电平
  delay(1000); //等待1000毫秒
  digitalWrite(LED, LOW); //低电平
  delay(1000); //等待1000毫秒
}

3_按钮控制LED

#define LED 5
#define botton 0 

void setup() {
  // put your setup code here, to run once:
  pinMode(LED, OUTPUT);
  pinMode(botton,INPUT_PULLUP); //内部上拉
}

void loop() {
  // put your main code here, to run repeatedly:
  if(digitalRead(botton)){
    
    digitalWrite(LED,HIGH); //高电平
    
  }else{
  
    digitalWrite(LED,LOW); //低电平
  
  }
