Membuat Mp3 Wireless Menggunakan DFPlayer Mini + Remote

Bagi teman-yang ingin membuat project ini. alangkah baiknya mempelajari terlebih dahulu step by step tentang modul yang akan digunakan di project kali ini, seperti Remote IR, 3 Wire LCD, dan DFPlayer Mini. teman-teman bisa mempelajarinya melalui link dibawah ini.

Selain itu yang perlu diperhatian lagi adalah File yang akan dimasukkan ke dalam SD Card, betnuk file harus berupa Ekstension Mp3, dan nama file harus berupa angka yang dimulai dari 0000-9999, untuk contoh, jika teman-teman mempunyai file lagu "Nissa Sabyan-01.mp3" teman-teman harus merubah nama file nya menjadi 0001.mp3 atau 0001Nissa Sabyan-01.mp3. karena modul DFPlayer akan mengekseusi Nomor File bukan Nama File.

Setelah File yang akan dimasukkan ke SD Card sudah siap, maka masukkan file tersebut kedalam sebuah folder yang diberi nama mp3. folder mp3 inilah yang di masukkan kedalam SD Card.
