Hey,
I have simply copied the example Sketch H, only adjusting the LED pin to 13.
Original:
#include <avr/sleep.h>
#include <avr/wdt.h>
const byte LED = 13;
void flash ()
{
pinMode (LED, OUTPUT);
for (byte i = 0; i < 10; i++)
{
digitalWrite (LED, HIGH);
delay (50);
digitalWrite (LED, LOW);
delay (50);
}
pinMode (LED, INPUT);
} // end of flash
// watchdog interrupt
ISR (WDT_vect)
{
wdt_disable(); // disable watchdog
} // end of WDT_vect
void setup () { }
void loop ()
{
flash ();
// disable ADC
ADCSRA = 0;
// clear various "reset" flags
MCUSR = 0;
// allow changes, disable reset
WDTCSR = bit (WDCE) | bit (WDE);
// set interrupt mode and an interval
WDTCSR = bit (WDIE) | bit (WDP3) | bit (WDP0); // set WDIE, and 8 seconds delay
wdt_reset(); // pat the dog
set_sleep_mode (SLEEP_MODE_PWR_DOWN);
noInterrupts (); // timed sequence follows
sleep_enable();
// turn off brown-out enable in software
MCUCR = bit (BODS) | bit (BODSE);
MCUCR = bit (BODS);
interrupts (); // guarantees next instruction executed
sleep_cpu ();
// cancel sleep as a precaution
sleep_disable();
} // end of loop

What am I missing?
