Hi folks.
Im thinking of a circuit which will incloude timer and memory. What i want to do is , i ll build a circuit which will count time when it energeized and will stop counting time when its turn off. Although energy gone ,memory will not forget the count. Like car’s km counters. But it will be electronic and it will has a small pcb area.
Is there any example of circuit like that. ?
And also i forgot to tell the counter will reset every year.
That is all idea may its stupid. But i really wondering how can i do and whixh components should i use.
THANKS.
