Gambar sistem komunikasi antara android dan arduino dengan kabel usb.
oke.. kali ini saya akan membagi tutorial mengenai bagaimana melakukan akses data antara android dan ardino melalui komunikasi USB. Arduino disini yang saya gunakan adalah arduino mega ADK yang mana didalamnya sudah include firmware untuk android, sehingga device android yang anda gunakan akan dapat langsung mengetahui device anda. untuk dapat melakukan akses anda dapat menggunakan library adb.h yang dapat anda download langsung di bawah ini. berikut adalah listing program untuk membaca sensor ultrasonik yang kemudian akan dikirim ke android.
