Im looking to build a digital clock that uses power (and line freq) for the circuity. Ive got everything designed up to the counter. The problem Im having is how to make the minutes count. Ive got 1 Hz ( divide by 16 from 60Hz and you get 1Hz) for the seconds. Ive come up with 2 solutions:
1) Use two timers to count to 59 Seconds
2) Use Another Divide by to obtain the frequency of 1 Pulse Per Minute.
I dont want to do 1, since it will raise costs, and the size of the board (plus I have no use for a seconds Counter). The problem with 2 is that I dont know what frequency 1 Pulse per 1 Minute is (since there are 60 seconds in one minute, then 60 Cycles per minute =1 minute)
Does anyone know what the frequncy is? Or is there another option?
