+/**
+    Some tips and tricks:
+    -   To use the built-in LED:
+            DigitalOut led1(LED1);
+            ...
+            led1 = 1;
+    -   To delay the call of a function:
+            Timeout someTimeout;
+            ...
+            someTimeout.attach(callback(&someFunction), 0.5) with 0.5 as 500 milliseconds
+    -   The variables that are used in interrupt callbacks have to be volatile, 
+        because these variables can change at any time. Therefore, the compiler is not 
+        going to make optimisations.
