Hello, my name is Josip and I am from Croatia. I have master's degree in electronics. After seeing your schematic i found some errors. You connected motors directly to arduino which can have several drawbecks, but most important is the effect of back emf. I suggest to do opto isolation using one optocoupler for each servo wich will not cost you a dollar on ebay. Second, i propose using opamp to amplify audio signal from mp3. After opamp use RC filters to get one signal for each frequency. I am opened for a talk, and please feel free to contact me. Price will be changed accordingly to our agreement and your specs. Looking forward to work for you. Best regards, Josip
