Mastering Arduino in Ten Days: DS1307 Digital Clock
Background Knowledge The DS1307 is an I2C interface real-time clock (RTC) chip, primarily used for independent timing (data retention during power loss), providing accurate year/month/day/hour/minute/second information for devices like Arduino and microcontrollers. It is one of the most commonly used timing modules in hardware DIY projects. 【Core Features】 Independent Timing: Built-in 32.768kHz crystal oscillator with … Read more
