 /*
- * Blink
- *
- * The basic Arduino example.  Turns on an LED on for one second,
- * then off for one second, and so on...  We use pin 13 because,
- * depending on your Arduino board, it has either a built-in LED
- * or a built-in resistor so that you need only an LED.

+  Blink
+ 
+ Turns on an LED on for one second, then off for one second, repeatedly.
+ 
+ The circuit:
+ * LED connected from digital pin 13 to ground.
+ 
+ * Note: On most Arduino boards, there is already an LED on the board
+ connected to pin 13, so you don't need any extra components for this example.
