The program first worked fine on my components but now its not working I try to upload code again and again but it's not displaying anything and not even connecting to wifi what thing am i doing wrong?

How did you connect the LCD with the bread board? My LCD is soldered with I2C!

in website its shows field value unavailable and lcd is not display anything
Which software is used to upload the program to Nord MCU board ? Where I can write the program?
Arduino IDE.
@@TechTrendsShameer is laptop required or phone is enough..plz tell im having an exhibition
What are the libriares we have to install
Thank you sir. It was really helpful and working
nodeMCU has only one analog signal sensor which A0, why u use the sensor D4
D4 I am using for DHT 11 sensor which is a digital pin. For gas sensor, I connected A0
@@TechTrendsShameer dht11 sensor is supposed to connect analog pin right or??

@@TechTrendsShameer thanks for clarifying..
@@TechTrendsShameer because I wanted to use nodeMCU for my IoT project but then realised it's not compatible
Thank you for this tutorial ❤
My LCD is not displaying anything pls help
Adjust the potentiometer and try.
Sir error showing in lcd.begin
Send me the error message.
getting error DHT.h file not found
From Arduino IDE -> Manage Libraries. Search for DHT and click Install.
useless, too many shortcuts
Since you didn't understand, it doesn't mean this is useless.
LCD not working even after adjusting the potentiometer
I2C module red light not blinking
Plz help...
Use this library.

@@TechTrendsShameer already installed
Showing Blynksimpleesp8266.h nit available. Not working 😔
Install the Blynk library from Arduino IDE -> Tools -> Manage Libraries.
