Anenometer - Blynk

Solved
1

Hi. I need connect anenometer to ESP8266 Devkit but i dont know how i can change sketch…
Here is sketch for Arduino and this sketch is working but in sketch is not declare pin D3…
Thanks.

const int m_time = 5;      //Meassuretime in Seconds

  time = millis();
}

void loop()
{

  meassure();

  Serial.print("Windgeschwindigkeit: ");
  Serial.print(wind);       //Speed in Km/h
  Serial.print(" km/h - ");
  Serial.print(wind / 3.6); //Speed in m/s
  Serial.println(" m/s");

}

void countWind() {
  wind_ct ++;
}

void meassure() {
  wind_ct = 0;
  time = millis();
  attachInterrupt(1, countWind, RISING);
  delay(1000 * m_time);
  detachInterrupt(1);
  wind = (float)wind_ct / (float)m_time * 2.4;

Thanks:-) I try.

So it is working. Thanks

Hi, may I know whats the meaning of #include <version.h> ?

6

Hey @Ariqah_Huwaida I guess you’re asking about the #include <version.h> because you can’t upload sketch to your board, am I right ?

7

Yes. Thats right

8

I need to complete my project but I dont know how to make the coding of anemometer, esp8266 connect to the blynk.

9

Can you help me?

10

You probably have an outdated arduino core for the ESP8266, update to the latest version.
also update the arduino ide to the latest version as well.

12

@Ariqah_Huwaida Your question is very odd, because neither of the sketches in this three and a half year old topic contain the line #include <version.h>

I guess that means that your question isn’t actually related to either of these two sketches, so I assume that you’ve posted the question in the wrong topic?

Pete.
