Help with numeric input

Need Help With My Project

Hi blynkers!
I’m trying to use the numeric input, but I not sure what I’m doing wrong

The numeric input is on V2 and I’m trying to use it with a button on V3

More info on what you want it to do, what it is doing and what you have tried, will go a long way… not too many are going to read through your code to figure all that out.

3

The idea is when I press V3 it needs to read the number um the numeric input to send the right comand to the air conditioning

e.g. If the numeric input shows the number 18 it has to send the IR code of 18 degrees

4

Take a look at my water tank project… Water Tank Level Indicator with Low Level Warning Notifications . I’ve used numeric input which is activated on and off with a button widget. With a slight mod to the code you maybe able to achieve what you need.

So… the problem is that in order to read values from Virtual Pins, you cannot do things like

... V2 == 18

You need to use the function BLYNK_WRITE(V_PIN), that is called every time the value held by V_PIN is changed by your app.

What I would do is set a global variable and have this function modify it every time the value in V2 is changed.

Something like this:

int temp;

BLYNK_WRITE(V2) {   

  temp = param.asInt(); // Gets the value stored in V2 as an integer

}
