+  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.
