아두이노에서 ESP8266 사용하기
- 아두이노 IDE는 1.6.4 이상의 버전을 설치
- 아두이노의 환경설정에서 추가적인 보드매니저 URLs에 다음과 같이 입력
http://arduino.esp8266.com/stable/package_esp8266com_index.json
- 툴 > 보드매니저에서 ESP8266을 검색후 ESP8266 보드를 설치한다.
- 설치후 툴 > 보드 메뉴에서 가지고 있는 ESP8266보드를 선택한다.
- 이 보드의 관련 정보: https://github.com/nodemcu

ESP8266 Blink by Simon Peter
Blink the blue LED on the ESP-01 module
This example code is in the public domain
The blue LED on the ESP-01 module is connected to GPIO1
(which is also the TXD pin; so we cannot use Serial.print() at the same time)
Note that this sketch uses LED_BUILTIN to find the pin with the internal LED
*/
void setup() {
pinMode(LED_BUILTIN, OUTPUT); // Initialize the LED_BUILTIN pin as an output
}
// the loop function runs over and over again forever
void loop() {
digitalWrite(LED_BUILTIN, LOW); // Turn the LED on (Note that LOW is the voltage level
// but actually the LED is on; this is because
// it is acive low on the ESP-01)
delay(1000); // Wait for a second
digitalWrite(LED_BUILTIN, HIGH); // Turn the LED off by making the voltage HIGH
delay(2000); // Wait for two seconds (to demonstrate the active low LED)
}
