Writing SOP Logic Expressions and AOI Circuits

[@Sarahbuildsstepsequencers]

Hi, Joe. I am an electronics hobbyist and I can’t figure out how to make a specific circuit and I’m hoping you can help me, please. I need a cmos circuit with a common cathode numeric display that *only* counts from 1 to 8 then starts over at 1. No 0 or 9. Could you possibly demonstrate a circuit that does so?

Hi Sarah, There are lots of IC's that will allow you to set a count range. I can email you a screen shot of a 1 to 8 counter using a 74193 if you would like.
