Ive been asked to create a roaming 7 day alarm for college. This alarm must trigger a lamp (output), after the input, which i am using to simulate an alarm, has been pressed 10 consecutive times in a 7 day period. if it is pressed less than 10 timesin a week, then any alarm that is older than 7 days must not be counted, but all other alarms that are younger than 7 days kept.
I am using N/o, N/C contacts,as well as timers, (various types i.e. off delay, on pulse one shot etc) counters and counter resets and I am getting absolutly nowhere.
I am using the Zelio programme if anyone is aware of this.
I cannot use 7 day clocks or shift registers.
The Attempt at a Solution
i have tried to use timers to trigger off by a pulse, then count for 7 days, and if another pulse come into trigger the next timer off, and so on for 10 timers, but i can seem to get it to work.
Ive been at this for at least 10 hours oveer a 3 day period now, and I am getting fustrated!
Any help would be much appreciated.
