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 ...

If you’re dealing with RF, you’ll probably have the need to generate a variety of clock signals. Fortunately, [Jason] has applied his knowledge to build a SI5351 library for the Arduino and a ...

Some of the first steps toward working with Arduino is understanding how to write code for it. The good news is that it's made with beginners in mind.

You address it as Arduino. Then it beeps and you can speak a command. There’s also a real-time clock module. Setting up the MOVI is simple: recognizer.init(); // Initialize MOVI (waits for it to ...

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 ...

Maker Michael Klements has built a unique electromechanical clock using a little Arduino hardware, code, and 28 servos, which tilt panels to reveal the ...

Arduino enthusiasts or those looking to build a binary clock may be interested in a new shield created by developer Marcin Saj. The binary clock shield ...

Alarm clocks are cheap and abundant, but they’re pretty boring. If you want to make your own, Instructables user Paranoid Legend shows you how to build one with an Arduino.

Instead, Make shows you how to build an internet-connected alarm clock using an Arduino and Google. All you'll need is an Arduino Yúnm a touch screen, a USB speaker, and a few cables.
