In the error message we can see the script contains:

where setPeriod is a method member of the TimerOne class. TimerOne.setPeriod(interval) would be an error; you can only apply setPeriod to an instance of TimerOne, such as Timer1. So, no, replacing Timerone with TimerOne will not work. Replacing it with Timer1 might.

Ah right (not wishing to threadjack)

A simple example of class would be “int” and the variable XYZ would be of class int.

(Of course technically speaking int is a fundamental type, not a class, but that’s C++ for you.)
