The dot matrix clock was built without the use of a regular Arduino board but uses the ATmega168 with Arduino bootloader and assembled on a breadboard. An RTC clock compensated by temperature is used ...

There are so many nice hacks in [Joekutz]’s retro LED display project that it’s hard to know where to start. There’s his DIY LED display controlled by an Arduino UNO. To have some text or picture for ...

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’re surprised we haven’t seen this kind of clock before, or maybe we have, but forgot about it in the dark filing cabinets of our minds. The above picture of [danjhamer’s] Matrix Clock doesn’t quite ...

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 ...

Okay, I knew this would happen - one Arduino clock leads to another. Take a look at a clock that tells the time in terms of the first 192 digits of Pi, via a 32 x 8 LED matrix... Dubbed the Pi Day ...

Electronics enthusiasts or those looking to learn more about electronics may be interested in a DIY word clock which has been created using a little Arduino programming, Arduino development board and ...

Your smartphone makes a great smart alarm clock, but not everyone wants their phone next to their bed all the time. Instead, Make shows you how to build an internet-connected alarm clock using an ...

Arduino enthusiasts interested in creating a changeable RGB LED matrix might be interested in the new Pixie Chroma displays created specifically for the Arduino platform by the engineers and develop ...
