I have a project where I will need to read out many (so so many) analog inputs (different resistor values). After googling around I learned that multiplexers will really help me out here. I have an idea (and a schematic sketch attached) but I seeing how I’m fairly new to this business I was hoping some of you more experienced folk can take a look and maybe detect foreseeable problems.
I use and Arduino mega in combination with about 48 multiplexers (HC4067). All the multiplexers are connected to 1 analog input. 4 Digital outputs are used to control all the input selectors on the multiplexers. 48 Digital outputs are connected to the individual enable ports on the multiplexers to select which multiplexer to read from.
I have a gut feeling this might not work so easily as I hope… Any tips or feedback is appreciated!
