//Mux_Shield_AnalogIn_Example

/*
This example shows how to read and store all 48 pins as analog inputs into arrays and print the results over serial.
Multiplexer pin inputs that do not have a voltage reading (i.e nothing connected) will have erratic values.

To simplify this code further, one might use nested for loops or function calls.
