Virtuabotixrtc.h Arduino Library -

An Arduino does not keep track of time (hours, minutes, seconds) accurately once powered off. A Real Time Clock module, powered by a small coin cell battery, keeps ticking even when the Arduino is turned off. This library allows the Arduino to:

Important: The DS1302 requires a backup battery (usually a CR2032) to keep time when the Arduino is unplugged. Ensure the battery is installed and has a charge above 2.5V. virtuabotixrtc.h arduino library

: virtuabotixRTC(uint8_t CLK, uint8_t IO, uint8_t CE) initializes the digital pins used for communication. An Arduino does not keep track of time
