How to use a RTC With an Arduino UNO R3 to Create an Accurate Clock

Hello
I have another version of RTC # Gravity: I2C SD2405 RTC Module

I used the same codes - compiling and upload was ok. But running it with the code, the output was
12:05:55.619 → ⸮f⸮`⸮⸮~~Couldn’t find RTC

Any helps/suggestions are greatly appreciated. Thanks.
