mp3 player with remote Project help and recommendation

Hi all,
i would like to make an mp3 player that has they following options/modules...
mp3 playing
RF remote control (for distance more than 250m range)
GSM
external loud speaker
battery (Lithium)
a small LCD

Which arduino board do you recommend? Also which modules do you think will be best for me?

Regards,
Nicos

First recommendation is to give your posts meaningfully titles. Like in your case MP3 remote player.

An arduino can't play MP3 files so you need a chip to do this.
You would be better off using an arduino to press the buttons on a cheap MP3 player in responce to a remote. Not sure where the GSM fits into the picture though.
Use a UNO

You want to remotely control an MP3 player from over a quarter of a kilometer away?

it will be used as a 'scarecrow' in the fields by a friend of mine :slight_smile:

why not just put a speaker in the field and run a wire to a mp3 player at your friends home. Or just put a radio out in the field and put a radio transmitter in your friends house.
