Esp8266wifi.h library not found error

Hi, Madhukesh after a long time I uploaded the sketch successfully and it’s connecting to my hot-spot.
I added one line to the sketch in starting of the sketch
#define BLYNK_PRINT Serial
and got output as in screenshot

IP: 0.0.0.0

This means that your ESP8266 isn’t getting a valid IP address, probably something to do with your hotspot.

It’s connected to my hot-spot and the IP address was showing below in the serial monitor.
Thanks for your cooperation and precious time and guidance.

I don’t understand what that means.

BTW, it’s MUCH better if you copy and paste your serial monitor data rather than posting screenshots.

I could not cover the whole screen of my computer screen while captuing the picture by my mobile and I have successfully connected it to my mobile hot-spot.

I will also post the correct circuit diagram when I complete it.

I made it and thanks for your cooperation, guidance and precious time.
