Can you let us know the problem you are facing? From your post, am unable to decipher that.

I’d say that’s your problem right there.

Read the Getting Started guides and take note of the bits about keeping your Void Loop() clean, the use of timers, and avoiding the use of delay().

@Cheryll_Cheryll_Dane Use the value display widget on Blynktied to a virtual pin. Use Blynk.virtualWrite(Vn, value) in your program. The value will show up on your phone Blynk UI. See examples for Value Display widget in the docs.

Okay, I’m going to drop out of this thread now, it’s too painful.
As I suggested earlier, you should read the Getting Started tutorials.
