Digital electronic clock circuit using CD4017 CD4518 and CD4511

Published on May 03 2011 // Timing control circuits

As shown in the digital electronic clock electronic clock circuit ASIC KD482FC seconds to do the base signal, multi-frequency digital circuit after the formation of points and the output respectively. One sub-display with LED digital tube; and the display when the pointer is to imitate the mechanical clock dial structure, through the light-emitting diode position on the dial to display. It is time accurate, new forms, it is for the amateurs of imitation, the circuit as shown. Circuit formed by the second time base signal circuits, sub-circuit and the time when the formation and display form and display circuit. The power circuit as shown below.
