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 ...

We have seen quite a few different geeky clocks before on Geeky Gadgets, the latest one is this cool Arduino Weather Clock built by Sean Carney. Sean took an antique clock and removed the mechanism, ...

Making a clock with a common microcontroller like an Arduino isn’t very difficult. However, if you’ve tried it, you probably discovered that keeping track of wall time is difficult without some ...

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 breakout ...

Makers considering building a Nixie tube clock, may be interested in a new Arduino shield which has been specifically created to make building a nixie tube clock and easier process. The Nixie Clock ...

Sick of telling time the old way? Spice up your time-telling time with the open-source, hackable and Arduino-based DOTKLOK. Basically, you can get a bunch of different ways to tell time. Different ...
