As much as I don't want to go with a microcontroller, it appears the quickest path between point A and B will be by programming instead of hard wire dedicated circuits. So I am looking at the Arduino family of products as my path forward. Project #1 is I/O heavy. Using a micro, it appears I will need 3 inputs and 3 outputs per "station", and at least 8 stations. To start I need 24 inputs and 24 outputs, plus other functions that are required but have not been incorporated yet.
So my question is: Has any one developed an I/O expansion module for the Arduino to expand the amount of I/O that can be addressed by the chip? I have an idea forming, but would rather see if this has been done before and/or if there is a module available to do it before I roll my own.
