Daisy-chained shift registers and 7-Segments display on

Another open hardware project published in two parts on few days ago. Read part 1 and part 2 articles of the project.

The first article introduces a small board that, using four daisy-chained shift registers, enhances Arduino with a general-purpose extension of up to 32 output ports; it works on most Arduino boards and Arduino-compatible devices. The second article completes the discussion introducing a practical application: controlling four 7-Segments LED displays with only three Arduino Pins, simply using the daisy-chained shift registers.

The PCB only or the fully assembled circuits are available on and, while more technical details can be read on the Arduino Kits section of the Projects in the pages from where sample software, the  Arduino libraries and the data sheets are available for free download.
