I am trying to figure out a circuit that will activate a relay for two hours each time the button is pressed up to at least four times (8 hours).
So if it is pressed once it will activate the relay for two hours and if it was pressed twice 4 hours, etc.. Up to 8 hours minimum.
Ive been successful using a MC68RS08KA2 MCU to do the delay for 2 hours but I cant figure out a loop to accumulate additional time. Ive also used a 555 to get the two hour delay but not a way to get the additional time.
Does anyone have a suggestion of a simple circuit that will do the same thing with or without a 555 or MCU? Is there another chip out there that would make this simpler?
Is there a circuit that will allow a 555 or another chip to repeat based on a button input?
Any creative thinking would be appreciated.
Thanks in advance.
