I saw on the http://www.e-licktronic.com website that there is two library for arduino.
One is SRIO library to use with shift register 4021 and hc595 here http://www.e-licktronic.com/en/content/19-tutorial-library-srio
and the second is PotMUX library who allow you to use multiplexer 4051 without extra code simply with one function "Pot.Read".
I would liket to know if somebody already test it?
