Hi.
Here is the complete error message generated by Arduino IDE 2.1.0 when compiling clock_number_3.ino.

Please support me, how to correct this.

Many thanks!

Compilation error: 'RTC' was not declared in this scope

Hello

I developed this project ~3 years ago , The version of the DS3232RTC library by JChristensen used was 1.2.6.

In 2022 he released 2.0.0 Arduino DS3232RTC Library 2.0.0

Which as you can see from release notes in link is not backwards compatible. That is what is causing the compilation errors.
