ESP8266的LED灯

步骤

让esp8266的LED灯一闪一闪的…
在Arduino中配置好,根据自己的配置…

工具-开发板-··NodeMCU 1.0

工具-端口-COM4(我的是COM4…)

下面这段代码就是文件-示例-Basics-Blink

一定要注意加上一行代码#define LED_BUILTIN 2

Blink

Turns an LED on for one second, then off for one second, repeatedly.

Most Arduinos have an on-board LED you can control. On the UNO, MEGA and ZERO
it is attached to digital pin 13, on MKR1000 on pin 6. LED_BUILTIN is set to
the correct LED pin independent of which board is used.
If you want to know what pin the on-board LED is connected to on your Arduino
model, check the Technical Specs of your board at:

*/
#define LED_BUILTIN 2
// the setup function runs once when you press reset or power the board
void setup() {
// initialize digital pin LED_BUILTIN as an output.
pinMode(LED_BUILTIN, OUTPUT);
}

// the loop function runs over and over again forever
void loop() {
digitalWrite(LED_BUILTIN, HIGH); // turn the LED on (HIGH is the voltage level)
delay(1000); // wait for a second
digitalWrite(LED_BUILTIN, LOW); // turn the LED off by making the voltage LOW
delay(1000); // wait for a second
}

最后,项目-上传
