Here, a common cathode 7-segment LED display is connected to Arduino for displaying the digits. The code (Arduino sketch) allows push button increment of the counter from 0 to 9. The whole circuit can ...

Recently, we published an entry-level Arduino project with a single seven-segment LED display. Although it’s an amazing DIY project, we noted that most of the readers are looking for more advanced ...

The timer is simple enough, being driven by an Arduino board, while the display is pre-formed into the 3D-printed case. The hot glue fills the enclosures behind each segment, and after several ...

A large 7-segment LED display that’s visible in the glare of his bench lighting and not just in subdued illumination. Future plans include replacing the messy wiring with stripboard sections for ...

Logic 0 will turn on a segment, and logic 1 will turn it off. A lookup table in the MCU code is used to generate the desired display. U4 can be two sections of a 74HC14 or one 74LVC2G14/NC7WZ14.

A mechanical 7-segment display powered by a keyboard brings a whole new level of innovation to the table. Curious how a regular keyboard can work with a 7-segment display?
