+  Button
+
+  Turns on and off a light emitting diode(LED) connected to digital pin 13,
+  when pressing a pushbutton attached to pin 2.
+
+  The circuit:
+  - LED attached from pin 13 to ground through 220 ohm resistor
+  - pushbutton attached to pin 2 from +5V
+  - 10K resistor attached to pin 2 from ground
+
+  - Note: on most Arduinos there is already an LED on the board
+    attached to pin 13.
