ur main routine(ie. the isr) should count the interrupts(one on a main reg. and also on a temp. reg) as well as call a timer-routine which will lit the led for one sec.As the counter reg.=5, u reset the temp.reg(ONLY TEMP REG),call another subroutine which displays the content of the
main reg.(which now has the total int.)
For display routine u can use either
leds or lcds. done?
