Hi @amir na, Welcome and nice to meet you. Ah, let me see. Your project using PCM1082 and MAX4466 is interesting. Let me list the reasons that why you should use Rpi Python and not Arduino for the final human interface part of your project: (1) Arduino is just a micro controller, but Rpi is a computer, much like, but a bit smaller than the powerful but evil WinTel PC, with Win10, (2) Rpi python is very good to develop hardware and software projects, for either newbies and ninja alike (even bit guys like Google is loving it and use for their AI/TensorFlow projects!), …
