RTC Setup: The DS1307 RTC module keeps track of the current time and date, even when the Arduino is powered off. The RTC.set() function is used in the setup() to initialize the time to 12:23:01 on 5th ...

Objective: The purpose of this lab is to build a standalone prototype Arduino Uno clock with the skills learned throughout the labs of this course. This clock gadget will expand and test our abilities ...

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 ...

In this article you will learn how to make a digital clock using Arduino and the DS1307 RTC IC. What is DS1307 IC actually? Well, it is a Real Time Clock (RTC) IC that is simple to use, low cost and ...

PLEASE NOTE:- In some editions fo the Magazine (GB, DE), the Temprature sensor is listed as a DS1820 - This should read DS18B20. The DS1820 is an old part and does not function correctly in this ...

I like this. Following on from the creative use of LEDs with the Periodic Table, check out this smart shelving system, similarly driven by an Arduino and using LEDs, that serves as a clock. Not a ...

We’re big fans of the impractical around here at Hackaday. Sure there’s a certain appeal to coming up with the most efficient method to accomplish your goal, the method that does exactly what it needs ...

Makers looking for a project to keep them busy this weekend may be interested in a simplified version of the Domino Wall Clock created by the Carbon Design Group. Instructables member Kothe has kindly ...

A word clock – a clock that tells time with words, not dials or numbers – is one of those builds that’s on every Arduino neophyte’s ‘To Build’ list. It’s a bit more complex than blinking a LED, but an ...
