setDS1302Time(sec, min, hour, dayOfWeek, dayOfMonth, month, year) : Used once in the function to initialize the clock. updateTime()
To use this library, you will typically need the following components:
Restart the Arduino IDE to ensure the library is recognized. 3. Wiring the DS1302 to Arduino The DS1302 requires three data pins in addition to VCCcap V sub cap C cap C end-sub GNDcap G cap N cap D
| Problem | Likely Cause | Solution | |---------|--------------|----------| | Reads 85:85:85 | RTC not initialized or first boot | Run the set-time sketch once. | | Time resets on power loss | Backup battery dead | Replace CR2032 battery on module. | | No Serial output | Wrong baud rate | Ensure Serial.begin(9600) matches monitor. | | Compilation errors | Wrong library installed | Remove other DS1302 libraries (e.g., DS1302RTC). | | Garbage values | Floating pins | Add 10k pull-up resistors on CLK/DAT/RST or use shorter wires. |
The VirtuabotixRTCH Arduino Library offers several features that make it easy to integrate the RTC module with Arduino boards:
