How it works
BCD to 7seg Counter is modified to suit the Simplified SoP equation for each segments. See the repo for SoP computation.
How to test
All toggle switches in zero position and clock switch on for auto runner. Individual BCD bits can be toggled using corresponding inputs with clock switch off.
