Sure. maybe you can find a completely different solution for me
So I'm trying to "demultiplex" an array of 12 switches arranged in a 3x4 manner, one of those keypad digits thing.
It comes with 12 switches multiplexed to 7 pins, 3 for one side, 4 for the other, i want to rearrange it so that a i have all 12 pins available.
My idea was to have this circuit connected twelve times from each "anode" to each "cathode", then when one switch is pressed, the voltage alternates only on those two pins that connect that switch, which would then be connected to some gate that would give me an output.
