BLYNK_WRITE(Vpin) Conditional

[Samuel_Rojas]

Greetings. I am needing to ask from the arduino the status of a button in the application.

I would like to place it in a conditional, if that button is activated together with other parameters evaluated in the hardware they should trigger some final elements.

Add details :
Arduino MEGA with Ethernet Shield
• Smartphone OS (Android)
• Blynk server
• Blynk Library version

You should start by reading this:

Using Virtual Pins to control physical devices

I thought I’d write a guide about how to use virtual pins with app widgets such as buttons, to control physical devices such as relays, LEDs etc… Why use virtual pins anyway? I’d always recommend using virtual pins over physical pins when developing your code. There are a number of reasons, but here are what I consider to be the main ones: Virtual pins are hardware independent. This means that it’s far easier to port your code from one hardware platform to another in future (when you realise…

It would probably be best to save the value from the vPin to a global variable, then call a function that evaluates this and your other parameters.
