Most users ignore the 31 bytes of NV RAM on the DS1302. However, VirtuabotixRTC.h exposes this through writeRAM() and readRAM() . This RAM is separate from the time registers and retains data as long as backup power is supplied.

This comprehensive guide will walk you through everything you need to know about the VirtuabotixRTC library, from its core functions to building a complete digital clock project. virtuabotixrtc.h arduino library

delay(1000); // Update every second

The virtuabotixRTC.h library uses a few critical functions for daily operation: Description virtuabotixRTC(clk, dat, rst) Most users ignore the 31 bytes of NV RAM on the DS1302

The real power of the Virtuabotix library is in data logging. Let's build a temperature logger that only records from 9 AM to 5 PM. virtuabotixrtc.h arduino library
