What do you do with 144 7-segment displays ... saving precious RAM on the Arduino. A clock wouldn’t be any good if it wasn’t accurate. A Tiny RTC supplies battery-backed time data.

Although it’s an amazing DIY project, we noted that most of the readers are looking for more advanced circuits using multiple seven-segment light emitting diode displays. Here is a simple, yet useful ...

[FilleK] had some time to spare and decided to build a cheaper substitute for a real nixie tube using a regular 7 segment LED display. We have already seen this hack before, in the Arduino-based ...

This is a simple 0 to 9 counter circuit constructed using Arduino! Here, a common cathode 7-segment LED display is connected to Arduino for displaying the digits. The code (Arduino sketch) allows push ...

Electronics designer Patrick Thomas Mitchell has returned once again to Kickstarter to launch his new Raspberry Pi and Arduino programmable timer aptly named the Ninja Counter. The programmable ...

Droplet and StackAR, developed by MIT’s Media Lab, allow users to set timers or program an Arduino using light-based communication. By pressing the tool against a screen, flashes of light can ...
