I have an arduino mega and 256 analog sensors that I have to read. I already did it with a lot of 4067 16:1 multiplexers. At first it took all of my pins. Then I paralleled the multiexers to use only 4 digital pins to Control them and played with the E of them to turn them on or off.
Now my question is : is there a 256 : 1 multiplex that operates in the 5v range so my mega can handle it (or even smaller arduino) or if not a 128:1,64:1, 32:1. In order to make my board simpler.
Thank you very much for your time reading this. Have a nise day.
