Virtuabotixrtch Arduino Library May 2026

The VirtuabotixRTC library is a popular Arduino library used to interface with Real-Time Clock (RTC) modules, most notably the DS1302. It allows Arduino microcontrollers to keep accurate time even when disconnected from a power source or when the main microcontroller is reset.

Example: set date/time helper

VirtuabotixRTC myRTC(6, 7, 8);

The DS1302 typically communicates via a 3-wire interface (CE, I/O, CLK). Connect them to your Arduino as follows (note: pin assignments can be changed in the code): virtuabotixrtch arduino library

VCC

The DS1302 module has 5 pins. Use the following typical connection for an Arduino Uno: DS1302 Pin Arduino Pin (Example) Description Power supply GND CLK / SCLK Serial Clock DAT / I/O Bidirectional Data RST / CE Reset / Chip Enable 3.

Benefits of Using VirtuabotixRTCH with Arduino

• Use it if: You have an Arduino Uno/Nano and a DS1302 module for a hobby project.
• Avoid it if: You need high accuracy, alarms, or ESP32/STM32 support.
