esp32② BlynkでLEDオンオフがespr2でもでけた、esp32-cam

---blynk by esp32---------------------

https://wak-tech.com/archives/1546 で遠隔Lチカでけた

https://github.com/blynkkk/blynk-library からライブラリを入手してインスト

あとは以下のとおり

#define BLYNK_PRINT Serial

#include <WiFi.h>

#include <WiFiClient.h>

#include <BlynkSimpleEsp32.h>

#define LED 32

//自分の環境に合わせて変更

char auth[] = " ";

char ssid[] = "";

char pass[] = "";

int LED_Flag = 0;

void setup()

{　 //LED settings

  pinMode(LED,OUTPUT);

  digitalWrite(LED,HIGH);

  delay(200);

  digitalWrite(LED,LOW);

  Serial.begin(115200);

  Blynk.begin(auth, ssid, pass);

  Serial.println("connected");

}

void loop()

{

  Blynk.run();

}

BLYNK_WRITE(V0)　

{　// BLYNK_WRITEはlibrayにあるのであろう　V0は32と紐付けられたのであろう

  LED_Flag = param.asInt();

  if(LED_Flag == 1){

    L_chika();   

  }

}

void L_chika(){

  Serial.println("LED ON");

  for(int i=0;i<5;i++){

      digitalWrite(LED,HIGH);

      delay(200); 

      digitalWrite(LED,LOW);

      delay(200);

  }

}

https://www.instructables.com/Blynk-With-ESP8266/　にしたがい

esp8266のライブラリを入手（blynkReleasse版）そのlibrariesのなかの

BlynkESP8266_libをarduinoのlibrarriesにコピー

上記のサイトにしたがいdev boardでesp8266_standaloneをえらぶ

でてきたコードを以下のように改変

https://wak-tech.com/archives/1546#i　を参考にLEDを13とした
