First of all let me thank you all for sharing your knowledge here, I learned much from this forum.
I would like to seek for advice on how to make simple timer whose purpose would be turning on device during lower electricity price which is 8 hours per day, using relay of course.
I did this using arduino uno and DS3231 RTC but then I thought about it and figured its quite an overkill in hardware for such a trivial function so I thought on using parts mentioned in the title
32k clock crystal on oscillator input to 4060 should give 500 ms period on the output of the O13 (most significant pin of 4060 14 stage binary counter)
My question is following: would you recommend interrupt for detecting raising 2Hz pulse edge or something else? Would you use attiny85 8 bit counters or simple while loop counting pulses to 57600/115200
Or maybe I missed something and there is even simpler solution to this?
I hope my question is clear, Im here to give any more details if needed.
