The best of the suggestions in the Twitter thread brings us to the Arduino Entropy Library, which uses jitter in the microcontroller clock to generate truly random numbers that can be used as seeds.

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… ...

A new Arduino-powered voice-activated clock has been created by Instructables user GeraldF6, who has kindly published step-by-step instructions enabling you to build your very own. This innovative ...

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

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 ...

Hard drive clocks are a dime a dozen on sites like Etsy, but Hacked Gadgets reader NatureTM went the extra mile and employed an Arduino to control the time and LED light show on the reflective ...

Just when you thought you’ve seen every strange variation of clock there is to see, we find one based on an Arduino that tracks the phases of the moon.

You'll need an Arduino, of course, and you'll also need a pair of laser pointers, a few servos and motors to make the lasers move as time passes, and of course, the IKEA BLANDA salad bowl ...

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. The alarm clock is ...

Check out this alternative 'Ternary' timepiece courtesy of an Arduino. If you remember the Made By Monkeys blog you'll know I like strange clocks and this one is no exception.
