Há como diferenciar o sd card do shield ehernet e o sd do mp3 player?
Que shields é que estás a usar? Tens um esquema? Já viste por acaso, que pinos são utilizados por ambos?

Agora preciso salvar o upload dentro do sd card do mp3 shield! Ja estou usando o sd card do ethernet shield para subir o webserver. Estou usando uma placa UNO, um ethernet shield hanrun, e um mp3 shield, todos acoplados. UNO -> ethernet > mp3 shield
*Nao acrescentei o código do mp3 shield, apesar de estar pronto, pois preciso primeiro conseguir gravar,o arquivo selecionado na html, no sd card. *
Pelos vistos não entendes Português...
