Sir" error compiling for board nodemcu 1.0 (ESP-12E Module). Define BLynk template id and blynk template name" asaa error araha hai plzz help sir

[@Pixelgaphy]

That a good project
can we use as soil sensor without using phone ?
and mixing of fertilizer also ?

[@VishnuPrasad-uv7hy]

Bro if u have the code please send me the program code for the project

Hello
Please please please send me libraries, i can't download them in Arduino IDE

[@satyjitdeshmukh5949]

In app they show offline

[@palakverma8667]

Hi, my soil moisture sensor is not giving any readings on blynk app, please suggest a solution

[@TechieLagan]

Sorry I won't lie , actually I don't know the solution...
But I think there may be some issue with the sensor, maybe it's not working..

[@muthukumar-bx2iz]

What can i do

[@rekha1780]

Bro in the app it is coming as offline

[@bruceleegamingSFA]

What is that wifi i mean who’s wifi? Is our personal wifi or any other source? Please answer

sir offline dekha raha h

[@varshand4785]

Bro my relay not working why

[@TechieLagan]

Check the connections

[@mehmetyatir9876]

where can we download the libraries?

[@TechieLagan]

in the arduino ide itself

[@hariprasadd2459]

😇😇😇

[@Triggeredinsaanmemes63]

Libaries kaha se dowload kare

[@TechieLagan]

There is a library section in Arduino ide. From there you can download the libraries.....
