In this tutorial you can learn how to make a digital clock using large 7 segment 2.3″ display (Common cathode) with RTC ds1307.
Circuit requirement:
* Arduino uno
* DS1307 rtc
* 7 segment 2.3” (Common cathode)
* 74Hc595 shift resister
* CD4511 7 segment driver
* 3v battery
* battery holder
* ic base
* 7-12v voltage source
* 10k resistor for rtc
