[王老师玩ESP32系列]第二课，第一个程序

1. 目标 
来一个 LED 灯闪的例子



2. 硬件
2.1 ESP32 开发板一个
2.2 led 一个
  
3.硬件接线
  
IO14 and ESP32 GND to LED

ESP32 接 LED


3.软件

 

void setup() {
  // initialize digital pin 13 as an output.
  pinMode(14, OUTPUT);
}
 
// the loop function runs over and over again forever
void loop() {
  digitalWrite(14, HIGH);   // turn the LED on (HIGH is the voltage level)
  delay(1000);              // wait for a second
  digitalWrite(14, LOW);    // turn the LED off by making the voltage LOW
  delay(1000);              // wait for a second
}

选对串口，能并能编译通过，就可以上传到ESP32板子，然后大家看效果吧
