DS1302 no such file or directory

This error message typically occurs when the Arduino IDE is unable to find the library for the DS1302 real-time clock module.

To resolve this issue, make sure that you have installed the DS1302 library correctly. To install the library, follow these steps:

1. Open the Arduino IDE.
2. Go to Sketch > Include Library > Manage Libraries.
3. In the Library Manager, search for "DS1302".
4. Select the DS1302 library and click on "Install".
5. Wait for the installation to complete.
6. Restart the Arduino IDE.

If you have already installed the library and are still getting the error message, make sure that you have included the library in your sketch. To include the library, add the following line at the beginning of your code:

#include <DS1302.h>

If you are still having issues, try restarting the Arduino IDE or resetting the Arduino board.
