I have a question. I'm making an alarm clock which switches on one motor for a constant time. There will be 4 alarms. THe clock will have no display. I was thinking of using four of these for setting the clock http://sos.sk/?str=371&artnum=S0... for setting the time and 5 buttons. WHen one of them would be pressed the time or one of the alarms would be set.
Unfortunately, these switches are VERY expensive and not on the store right now, so I was wondering if there's any other, better way of setting such a clock that comes into mind.
