Transfer parameter-value from loop to function

Projects Programming
8

Hello dear,

Ive done a little progress with your help. :slight_smile:
At the moment, the matching value of 5000 is passed to the function matching(), if button 1 is clicked. When we press button 2, the value of 2000 should be passed to the function matching.
The fault at this point is, that in case button 2 is clicked, the serial monitor still displays 5000.
So still pass the wrong variables with my code. :smiley:

For reference the current code, without mangling (:D):
