This is a library to handle Seiko's RX8010SJ RTC module with an arduino. Original datasheet can be found here. To set up your module, you only need to power up and use the i2c protocol to communicate ...

Here is the circuit diagram of a compact RTC module, based on the popular RTC IC DS1307, for your everyday microcontroller projects. The DS1307 ... a library for getting and setting time from a DS1307 ...

The DS1302 is supported by a few Arduino libraries and only requires three pins on the microcontroller to operate. ... (RTC) module with on-board, 20-ppm oscillator. A small, DS1302-based Real-time ...

The most popular RTC for the Arduino is the DS1307. However, it does have some drawbacks, the most notable of which is that its operating voltage is 5v, which means it cannot be used with 3.3v ...

No sharp edges for the Arduino crowd. Seriously though, cool test with the freezer…I hadn’t thought to try that. I dare anyone to do that with a DS1307 module.

RTC module has button battery for backup so the TIME will not reset. We have also built Alarm Clock using Arduino and using ATmega32 AVR Microcontroller , check them too. In this Raspberry Pi Digital ...
