Digital Clock Circuit Diagram Using Arduino. In the control of display i have used an arduino uno r3 and 02 ics of 74hc595 8 bit shift register with output latches. Connect pin 13 of ardunio to led.
In addition the module has a built in temperature sensor. This is my project of a digital clock with rtc real time clock using a led display of 4 digits and 7 segments including interesting features of temperature and humidity. Arduino digital clock without rtc.
On arduino from 0 throught 7 connect a throught dp to 4 digit display i e.
The clock uses the rtc module to accurately track time as well as the day month and year. By comparing the wiring diagram with the sketched functions you should start making sense of the circuit. Connect pin 13 of ardunio to led. Arduino digital clock without rtc.
