In the world of Arduino timekeeping, the RTClib (for DS1307/3231) often steals the spotlight. However, a significant niche of projects—especially those involving retro hardware, low-power logging, or budget constraints—relies on the DS1302 Real-Time Clock (RTC) chip. The library that serves as the primary software bridge to this chip is VirtuabotixRTC.h .
// Initialize the RTC object with your chosen pins: (CLK, DAT, RST) // My wiring: CLK=4, DAT=3, RST=2 VirtuabotixRTC myRTC(4, 3, 2); virtuabotixrtc.h arduino library
Provides access to the 31 bytes of non-volatile RAM built into the DS1302 chip. Simple Setup: In the world of Arduino timekeeping, the RTClib
: The updateTime() function must be called within the loop() to refresh the local variables before reading them. Basic Code Structure A standard implementation typically follows this pattern: // Initialize the RTC object with your chosen
