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.

In our time here at Hackaday, we have seen many display builds, but this one from [Brian Lough] has to be a first. He’s created a 7-segment display made from shoelaces, and it works rather we… ...

Get ready to witness something mind-blowing! 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 ...
