+====== void   ======
+The void keyword is used only in function declarations. It indicates that the function is expected to return no information to the function from which it was called.
+====Example:   ====
+<code arduino>
+// actions are performed in the functions "setup" and "loop"
+// but  no information is reported to the larger program
+void setup()
+{
+  // ...
+}
+void loop()
+{
+  // ...
+}
