MH Gerçek Zamanlı Saat Modülü - 2 - DS1302

DS1302 real-time clock module for keeping date and time with battery backup. The DS1302 is a low-power, trickle-charge real-time clock (RTC) chip that keeps track of the current time and date. It maintains counts for seconds, minutes, hours, day of the week, date, month, and year, automatically adjusting for months with fewer than 31 days and accounting for leap years up to the year 2100. It operates using a simple 3-wire serial interface (CLK, I/O, and CE/RST) to communicate with a microcontroller like an Arduino. The module typically features a backup coin-cell battery holder, allowing the chip to keep accurate time even when the main microcontroller loses power. Additionally, it contains 31 bytes of non-volatile RAM for basic data storage.
