If you’re going to discover digital logic, why not goal high? That’s what [Easton] as well as his good friend did when they built a clock utilizing only 4000-series logic chips. On a breadboard, no less.
For a 1 Hz clock, [Easton] as well as his good friend utilized a 4060 counter paired with a flip flop. This counts off 59 seconds until, with the assist of an as well as gate, the seconds counter rolls over to zero. After repeating that once again for the minutes as well as building a similar circuit for the hour, as well as [Easton] had a working 4000-series 24-hour clock.
The breadboard clock may not be the prettiest thing, or a textbook example of exactly how to prototype circuits, but that was fixed with [Easton]’s friend’s PCB design of a 12-hour clock. We couldn’t discover any type of pics of this, however we’re sure it’s awesome as well as a excellent method to discover about logic as well as design.
