I first want to thank you guys for the help and support you give to the community.
As a complete newby I have a project in mind. How hard would it be to make some battery powered led lights flashing, as well as to play some pre recorded music using some tiny speakers of 8 ohm, all of this activated using a specific three or four music notes. Let's say that I want to whistle 3 or 4 notes (let's say Do, Mi, La, Sol) and by doing so I can get some led lights to flash while the music sounds through the speakers. All of this using entirely arduino. Ideally, I would power the whole thing using some coin cell batteries.
I have no idea what kind of arduino board to use or how complicated could it be.
My only experience with programming was with visual basic when I was 12 and I found it to be fun, so I am hoping that this could be fun too.
Thanks a lot in advance.
