For DS1302 users, the main alternative is the library by Henning Karlsen (often named DS1302.h ). Karlsen’s library is more feature-complete, offering alarm support and better error checking. However, it is also larger and more complex. The VirtuabotixRTC library is often preferred for very small projects or when code simplicity trumps feature richness. virtuabotixrtc.h arduino library

This rigid pin mapping is critical: the library does not use any hardware SPI peripherals; it bit-bangs the protocol entirely in software. Accepts integers from 1 (Sunday) to 7 (Saturday)
