   Basic Ticker usage
-  
+
   Ticker is an object that will call a given function with a certain period.
   Each Ticker calls one function. You can have as many Tickers as you like,
   memory being the only limitation.
-  
+
   A function may be attached to a ticker and detached from the ticker.
   There are two variants of the attach function: attach and attach_ms.
   The first one takes period in seconds, the second one in milliseconds.

   The built-in LED will be blinking.
