/*
This is an "advanced" version of the Button example.

It uses a momentary button to start and stop a timer.
The timer will start if no timer is active, otherwise it will stop the timer.

A LED will light up and indicate if a timer is started or running.
The LED will turn of if the timer is stopped either through a button press or the website.
