My new project is to build an LED clock with 7-segment displays. I have a ring of 12 LEDs to signify the hour, and two 7-segments to show the minutes, with pulsing LEDs to indicate the seconds.
My problem is this: I need to make a counter that will count up to 59 for me (0 to 59) so that I can count a minute. If I can get a 555 to produce second pulses, then I can use this counter to control my minute decade counter. This in turn can control my second minute decade counter, and with the aid of a NAND gate, these two combined will control my two hour decade counters.
Can anyone advice me how to make a counter to count off 60 seconds? I don't really know where to begin, except with a 555 circuit giving off second pulses. Any advice would be much appreciated!
