After some research, it was determined that it would be relatively simple to have an Arduino convert incoming serial data into a parallel output to the printer. After some testing was performed on ...

the Arduino “Sketch”, more properly named firmware) covered extensively in the second part of this article, should be a bit complex. But the result is fascinating. We should use a cheap parallel shift ...

a good point for that chapter's "Things To Try" section would have been to suggest using two 595 serial-to-parallel shift registers to drive the LEDs, using up only 3 IO pins on the Arduino.

This circuit can be considered as a general purpose daisy-chained parallel shift-out register group for a total of 32 output ports that we can easily manage with our Arduino board (or similar ...

While newer Arduinos and Arduino compatibles (including the Hackaday.io Trinket Pro. Superliminal Advertising!) either have a chip capable of USB or rely on a V-USB implementation, the old fogies ...
