Hello. This is my first post. I am a beginner in electronics. I want to make a circuit to keep track of the hours that my water cooling system is running. It should start counting on power-up, then adding each second to the total time. On shutdown the total time should be stored. Also a button to reset the total time would be nice. Total time in hours should show on a small LCD. I know I need a 555 timer for sure, but I have no idea which chip I should use to store the total time. Any ideas please???
Thanks a lot
