I’ll expand on this a bit.
-
As I have said there is class code in our sketch which is responsible for checking to see if a physical switch is sitting at the same state as the last time it was checked.
.
The name given to this code is object.validChange() where object is the name we give in the class object definition, in this case, mySwitch, hence mySwitch.validChange().
- If input pin is at the same state as the last time checked, the class code returns the number 2, NOchange (2) .
- The class code returns the number 0, NOTvalidated (0), if the state on the input pin has changed but the class code needs a bit more time to make sure this change isn’t due to electrical noise or maybe the switch contacts are bouncing.
- And lastly, the class code returns the number 1, VALIDATED (1), when the input change has been stable for at least 50ms without any contact bouncing.

Yes, please give us the error message.
I will do the same here to see if an error comes up. -
Most often, it’s probably a spelling mistake
