Hi,
i m working on project which aims to develop a soil sensor which will display soil moisture and ph value on android mobile app.
i am using Arduino UNO, ESP8266, and Blynk app to display data. This is my first project using blynk.
the problem is when i just read data from sensor and display its value on blynk app it works well. But when i apply if conditions on sensor readings, to make it more easier for a common person to understand what is meant by this particular reading of sensor, it does not work. It gets connect to wifi but does not read any sensor value and displays nothing on app.
#define BLYNK_PRINT Serial
#include <ESP8266_Lib.h>
#include <BlynkSimpleShieldEsp8266.h>

char auth[] = "*********";
//char ssid[] = "*********;
//char pass[] = "*********"; // Corresponding Password
