Digits DIY Clock Kit Auto Display Time DIY Alarm Clock Soldering Practice Kit for Students and Diyers DC4.5V-5.5V"},"content":{"rendered":"<p>Description  1  This product is a 24 hour digital circuit clock  using CD4518  CD4511  CD4081  CD4013  CD4060 and other chips  The circuit does not contain a microcontroller  so there is no program  The hours  minutes and seconds can be adjusted  and it does not have an alarm clock function  This kit is mainly composed of a second signal generator  a counter  a decoding display  and a timing circuit  The second pulse is accurately divided by the high frequency signal generator to obtain a 1HZsquare wave signal  and the timing is relatively accurate 2  The second signal generator consists of CD4060 and CD4013  which generates asquare wave signal with a frequency of 1HZ  CD4060 is a 14 level binary frequency divider oscillator  It forms a 32768HZ oscillator with external resistors R44  R43  C1  C2 and Y1  After 14 levels of binary frequency division  asquare wave signal with a frequency of 2HZ is obtained at pin 3  CD4013 contains two independent D flip flops  One of the flip flops is configured as a binary counter through wiring  The second signal can be obtained by binary counting the input 2HZsquare wave signal  CD4518 is a double decimal adding counter  Use three CD4518s to time the hours  minutes and seconds  The hours are configured in 24 digit format  and the minutes and seconds are configured in 60 digit format  The counting result of CD4518 is output from pins Q0 Q3 to BCD decoder CD4511 in the form of BCD code  CD4511 converts the BCD code into a display segment code<\/p>\n\n    <div class=\"xs_social_share_widget xs_share_url after_content \t\tmain_content  wslu-style-1 wslu-share-box-shaped
