This is an Arduino based digital Clock to display real time on a 16x2 LCD using a DS1307RTC module. The date and time can be set via serial interface or push button switches. Features: Shows date and ...

The past month or so I’ve been playing with the Maxim DS1307 Real-Time-Clock and DS1621 Temperature Sensor ICs. I hooked them up to an Arduino Uno board with a Parallax Serial 16×2 Character LCD. I ...

-What you will need to have : LCD I2C library, an Arduino (ofc) and a lcd display (16 by 2 is good) You could use a non-I2C but you'll have to configure it by yourself :/ Features that i'll (maybe) ...

This Arduino based Real time clock is a digital clock to display real time using a RTC IC DS1307 which works on I2C protocol. Real time clock means it runs even after power failure. When power is ...

Controlling the signals sent to the slave clocks and keeping them synchronized are the main tasks of this master clock. The National Time synchronization protocol is supported by the firmware in the ...

The build is fairly bare-bones, using only an Arduino Pro Mini, RTC and LCD display. For the real-time clock, [Eric] used the ever popular DS3231 RTC. The software reads the time from the clock ...
