Can some one point me in the right direction for making an alarm for my clocks(both the bcd-binary and 7seg)
I would like that the alarm time is set with a DIP switch set.
I have tried using them but I run into some problems. When you decode 10 min(001-000) it works the 1 goes trough the switch to the transistor and turn on the buzzer. But when you get to 30min(011-0000) the 1 goes thought and turns on the buzzer. It seems like im missing a few gates somewhere but I cant figure out where.
For those tests I used only a bcd counter, a Dip switch, a transistor and a buzzer.
