I will make a project on DS3231 Time Set Arduino Real Time Clock With Serial Monitor. The DS3231 is a very accurate & widely used Real-Time Clock (RTC) module. This module is used in Arduino based projects. This module also works with Raspberry Pi. So let’s start DS3231 Time Set Arduino Real Time Clock With Serial Monitor.

Aug 06, 2010 · The DS1302 trickle-charge timekeeping chip contains a real-time clock/calendar and 31 bytes of static RAM. It communicates with a microprocessor via a simple serial interface. The real-time clock/calendar provides seconds, minutes, hours, day, date, month, and year information.
