  can run at the same time without being interrupted by the LED code.
  
  The circuit:
- * LED attached from pin 13 to ground.
- * Note: on most Arduinos, there is already an LED on the board
- that's attached to pin 13, so no hardware is needed for this example.
- 
+ * LED attached from pin A2 to ground.
+ * Note: on the chibitronics board, this LED is already attached

/* Blink without Delay
 
 Turns on and off a light emitting diode(LED) connected to a digital  


// constants won't change. Used here to 
// set pin numbers:
const int ledPin =  A2;      // the number of the LED pin

// Variables will change:
int ledState = LOW;             // ledState used to set the LED
