i am not able to write value on blynk widget
i can see distance on serial monitor
using esp8266
helpp
// defines pins numbers
const int trigPin = 12;
const int echoPin = 15;
// defines variables
long duration;
int distance;
float h;
#define BLYNK_PRINT Serial
#include <ESP8266WiFi.h>
#include <BlynkSimpleEsp8266.h>
char auth[] = “xxx”;
void setup() {
pinMode(trigPin, OUTPUT); // Sets the trigPin as an Output
pinMode(echoPin, INPUT); // Sets the echoPin as an Input
Serial.begin(9600); // Starts the serial communication
Blynk.begin(auth, “xx”, “xxx”);
}
int data()
{
// Clears the trigPin
digitalWrite(trigPin, LOW);
delayMicroseconds(2);
// Sets the trigPin on HIGH state for 10 micro seconds
digitalWrite(trigPin, HIGH);
delayMicroseconds(10);
digitalWrite(trigPin, LOW);
// Reads the echoPin, returns the sound wave travel time in microseconds
duration = pulseIn(echoPin, HIGH);
// Calculating the distance
distance= duration*0.034/2;
// Prints the distance on the Serial Monitor
Serial.print("Distance: ");
Serial.println(distance);
delay(800);
return(distance);
Blynk.virtualWrite(1, distance);
}
void loop()
{
Blynk.run();
data();
}
