Which Arduino pins do I connect to the DS1302?
Connect VCC and GND, then connect the clock (SCLK), data (I/O), and chip enable (CE/RST) lines to three digital pins. Use a DS1302 library that matches your board.
Does it keep the time when power is off?
Yes, if a backup battery is connected to the backup supply pin, typically a 3V coin cell on modules and breakout boards. Without a backup source, the time resets when main power is removed.
