If the RTC is currently being synchronized with the radio clock, this is indicated by a dot between minutes and seconds in the display. If both clocks are in sync, a colon is displayed. The software ...

This application note is intended to demonstrate an application using the DS1307 real-time clock (RTC) with a Microchip PIC microcontroller. The software example includes basic operating routines. A ...

Making a clock with a common microcontroller like an Arduino isn’t very difficult. However, if you’ve tried it, you probably discovered that keeping track of wall time is difficult without ...

This replica uses LEDs driven by an Arduino Nano and a real-time clock. Since the RTC gives hours from 0-23 and minutes and seconds from 0-59, a couple of shift registers and some modulo ...
