In a recent video our hacker [Electronic Wizard] introduces the 74HC595 shift register and explains how to use it to drive ...

In engineering circles, this circuit is better known as a 7447 BCD to seven-segment decoder/driver, but just using a single chip has little pedagogical value.

You can interface this type of display to a microcontroller using one or two output pins. The one-pin MCU interface employs a pulse-width-encoded output per segment.
