[esp32-wroom]基础开发

1、点亮LED灯

int led_pin=2;
void setup() {
  // put your setup code here, to run once:
  pinMode(led_pin,OUTPUT);

 
}

void loop() {
  // put your main code here, to run repeatedly:
 
  digitalWrite(led_pin,HIGH);
  delay(1000);
  digitalWrite(led_pin,LOW);
  delay(1000);
}

2、LED流水灯

//定义GPIO引脚数组
int pin_list[5]={13,12,14,27,26};
int num=sizeof(pin_list)/sizeof(pin_list[0]);

void setup() {
  // put your setup code here, to run once:
  for(int i=0;i
