I can't get the status of my push button on blynk

Need Help With My Project
1

Hello team im trying to run a motor remotly by connecting an output to the pin 2 everything is working fine but i want a feedback input to let me know that the motor is running i tried to use the pin number 6 with Blynk.virtualWrite function but still cant get any feedback when i simulate the input from 5v of the board and pin number 6

First things first, you MUST REMOVE THIS FROM YOUR VOID LOOP…

Having it in there is flooding the Blynk server with thousands of messages per second.

This piece of code executes only once, when the device boots, and it probably won’t read the value of pin GPIO6, as that GPIO isn’t declared as an INPUT in a pinMode statement, and even if it were then that declaration comes later in the code execution sequence.

I’m a bit confused why you’ve use the name BUTTON_VPIN for this, as that implies it’s a virtual pin rather than a GPIO on your board that you’re reading.
Do you realise that there is no connection whatsoever between the virtual pins/datastreams in Blynk and the physical pins on your board?

If you want to read a GPIO pin on a regular basis (lets say once every second) and update a Blynk virtual datastream with the result then you need to use BlynkTimer to call a function once per second.
That function should read your GPIO pin, and write the result to a Blynk virtual datastream.

You seem to be using a switch widget for this “motor running” indicator, but I would have thought than an LED widget would have made more sense.
