Digital electric clock circuit diagram
As shown in figure, digital electric clock circuituses electronic horologe special integrated circuit KD482FCas seconds time-base signal. Through the digital circuit multi-stage separate frequency, it formsminute and hour to output. The minute isdisplayed byLED digital tube; While hour display is the analog dial structure of mechanical pointer clock,and itis displayed by light-emitting diodes in the dial. It's timing accurately, novelly, so it is very suitable for amateur toimitate. The circuit is composedof thesecond time base signal form circuit, minute time formation-display circuit and the hour formation-display circuit.
