Servo motor controlling using NodeMCU and Blynk App

Servo motor controlling using IoT.

Servo motor rotating angle can be controlled using NodeMCU And android app(Blynk).

Required components

1. NodeMCU.
2. Servo motor.
3. power supply(you can use USB cable).

Code

#define BLYNK_PRINT Serial

#include <ESP8266WiFi.h>

#include <BlynkSimpleEsp8266.h>

#include <Servo.h>

Servo myservo;  // create servo object to control a servo

char auth[] = "YOUR Blynk AUTH CODE";

char ssid[] = "YOUR WIFI NAME";

char pass[] = "YOUR WIFI PASSWORD";

BlynkTimer timer;

void setup()

{

  Serial.begin(9600);

  Blynk.begin(auth, ssid, pass);

  myservo.attach(D2);//Servo motor connecting pin,You can change pin but be sure about PWM availabilty on that pin.

}

void loop()

{

  Blynk.run();

  timer.run();

}

  int x = param[0].asInt();

  int y = param[1].asInt();

  Serial.print("X = ");

  Serial.print(x);

  Serial.print("; Y = ");

  Serial.println(y);

  if (x <= 0 && y < 600)

{

    myservo.write(180);//left

  }

  else if (x == 1023 && y > 400) //right

  {

    myservo.write(0);

  }

  else if (x == 512 && y == 512) //stop

  {

    myservo.write(90);

  }

  else

  {
