ok, thanks manuel and niccolo, i order a nano board but i will try use the mini i have and post the results when the amp and player arrive a my home, greetings from mexico.

thanks manuel, i will use the mini pro, if i can do make to work i will post my results, do you think i can put diodes in the battery voltage to decrease the voltage to 5v?

this is the pinout of pro mini, i think have the same 13 pins and is 5v/16 mhz, what do you thinks guys?. I do not even have all the components to make a test, i hope this board works.

hi, skyone, greetings, one question, you think i can use a arduino pro mini instead a nano for this proyect or i have change much the code? thanks for the answer an this post.

thanks skyone I am in the process of buying everything, here in mexico they have no idea of the main components, so all buy from usa and hopefully in a month or two to have everything and start the project, if I have questions I hope you can help me . greetings.

Hi skyone, I have a question, in the diagram, in each ground line of buttons there is a resistance of 10 kohm (r2,r3,r4), this is correct because I do not see in the list of components. greetings from mexico.
