Designing a Real-Time Clock (RTC) using an Arduino is a useful project for timekeeping and timestamping in various applications. You can use a dedicated RTC module like the DS3231 or DS1307, which ...

Libary to manage the RTC-Module as an capsulated object for the DS3231 RTC-Modul. In the test-folder lies an Arduino-sketch, which can be used to test the libary when flashed to an Arduino Uno with ...

He’s made a real-time-clock module controlled by a rubidium frequency standard, and since it also includes a GPS clock he can track local time dilation effects by comparing the two.
