This project demonstrates how to implement a real-time clock using the DS3231 RTC (Real-Time Clock) module and an Arduino. The DS3231 module is a low-cost, highly accurate I2C RTC with an integrated ...

Arduino Real Time Alarm Clock DS3231 with TM1638. Arduino Clock with Battery backup (real time clock), Time, Date, Alarm, Temperature, TM1638 seven segment module output and input, Display Sleep mode.

Hardware -------- Because this is an extension of the original generator the basis will be the same Arduino Uno I was allready using. A prototype shield carries the real-time clock based on a DS3231 ...

The build relies on that old stalwart, the Arduino Uno, to run the show. It’s hooked up to a DS3231 real-time clock module so it can keep accurate time for long periods, as is befitting a clock.

Using an Arduino Mega, DS3231 Real Time Clock Module, Eight stepper motors 28BYJ-48 with ULN2003 Driver, 82 cm Wooden strip 19x19mm, Steel Wire 1m, 46 Washer head screw 4.2 x 14 mm, 16 Button head ...

For playing the music, it uses the BY8001 MP3 Player module and for the alarm clock it uses the DS3231 Real Time Clock module.
