An organic LED display interface is demonstrated on this project with an ARM7 microcontroller displays and analog clock face on OLED low power screen containing an 18-bit color range. An organic LED ...

Arduino boards have grown so popular, that the very name “Arduino” is almost synonymous with development boards. The flexibility and economics presented by their wide range of products make them a ...

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 ...

You can use a microcontroller to build a clock. After all, a clock is just something that counts the passage of time. The only problem is that microcontrollers can’t track time very accurately. They ...

Arduino is little open source circuit board that lets you create some fairly compelling projects with a few lines of code and some circuit boards. The latest addition to the project is LiquidWare’s ...

We have featured quite a few cool clocks here at Geeky Gadgets, and the latest one is the work of Andrew O’Malley, the DOTKLOK, which is an open-source Arduino digital clock. The DOTKLOK comes with a ...

You know those analog clocks which are nothing but a pair of hands on a spindle, distilling the function of the timekeeper down to its bare, concentrated essentials? The Black & White Clock is like ...
