I wish to create a very simple Turbo display, which will toggle only between HI and LO.
Planning to follow this guide: https://oldcomputer.info/hacks/ledhilo/index.htm
I ordered a 2 digit 7 segment display, but it is using only 10 pins, which to my understanding require some more sophisticated circuit to multiplex, otherwise both digits will display the same thing. All the examples I could find use a dedicated driver IC or an Arduino etc.
I already ordered a display with 16 pins, to be able to control each segment individually, but I wonder...
Am I missing something? Is it possible to use passive components (I have some NPN transistors, caps and resistors) to drive the 10 pin display?
