I need to send a value to blynk app

Hi there! I have a project that color sorts some skittles and i want to make an app with blynk to show me how many red, green, purple etc skittles i had sorted. I’m new to blynk and i dont know to send that number to app( i think it would work with virtual pins but i dont know how) , can anyone give me an ideea? thanks in advange

If you want to know how to use virtual pins then start by reading this:

I guess you’ll use something like the Numeric Input widget to enter the value, then you’ll retrieve that value in the sketch using param.asInt(),
