Wireless PlayStation 2 Controller dengan Arduino Uno

OCTOBER 31, 2011   ZERFANI YULIAS   76 COMMENTS

Sudah lama sebenarnya saya ingin mempunyai cara untuk mengendalikan Arduino, terutama yang sudah digunakan untuk aplikasi robotik, secara remote (dari jarak jauh). Ada banyak cara yang bisa dilakukan, tapi rata-rata masih lumayan kompleks dan belum cukup praktis untuk dicoba. Alangkah lebih bagusnya lagi kalau bisa mengendalikan secara wireless, wah itu akan banyak menghasilkan ide-ide proyek Arduino yang kreatif.

Nah, secara tidak sengaja ketemu artikel ini, PlayStation 2 Controller Arduino Library v1.0, buatan Bill Porter. Disitu dijelaskan tentang Library Arduino yang dibuat untuk mengendalikan Arduino menggunakan PlayStation 2 Controller. Artikel di sana menggunakan PlayStation 2 Controller yang menggunakan kabel. Hmm…kalau mau pakai yang wireless kira-kira bisa gak ya? Ya coba aja deh…

Akhirnya dibeli tuh ‘2.4GHz Wireless Magic Light-Tube Dual Shock 2 Controller’ seharga Rp. 150.000,-. Gambar-nya seperti di bawah ini.

PS2 Wireless Controller dan Wireless Receiver-nya

Ok, Wireless Controller sudah ada, sekarang download Library Arduino-nya, link-nya bisa dilihat di dalam artikel di atas, atau di sini. Ekstrak file tersebut dan copy folder PS2X_lib ke dalam folder libraries yang ada di folder Software Arduino (saya kebetulan pakai software IDE Arduino versi 22). Kalau anda sudah membuka IDE Arduino, tutup dan buka kembali agar library yang baru bisa terdaftar.

Siapkan board Arduino anda, saya kebetulan menggunakan Arduino Uno, dan pasang kabel USB-nya ke Arduino dan komputer anda. Buka file contoh program yang sudah disertakan di dalam folder PS2X_lib tersebut, file-nya: PS2X_Example.pde. Jalankan Verify/Compile (Ctrl+R) untuk memastikan tidak ada error dan library yang tadi di-copy sudah terdaftar. Kemudian lakukan Upload to I/O board (Ctrl+U). Apabila sketch sudah diupload tanpa error, lepaskan kabel USB dari board Arduino anda, saatnya kita menghubungkan PlayStation 2 Wireless Receiver dengan Arduino.

Kode program yang terdapat pada file contoh dapat dilihat di bawah ini.

Di dalam artikel Bill Porter terdapat gambar yang menjelaskan koneksi kabel yang ada di connector-nya PlayStation 2. Gambar tersebut diambil dari artikel yang dibuat oleh Curios Inventor tentang Interfacing a PS2 (PlayStation 2) Controller. Koneksi kabel pada konektor tersebut dapat dilihat pada gambar di bawah ini.

PlayStation 2 Connector Wiring

Jadi ada 9 pin di dalam konektor PS2 Controller, yaitu:

1. Pin Data
2. Pin Command
3. Pin Vibration Motor Power
4. Pin Ground
5. Pin Power 3.3V
6. Pin Attention
7. Pin Clock
8. Pin Unknown
9. Pin Acknowledge

Tetapi dari 9 pin tersebut, kita hanya akan memakai 6 buah saja, yaitu Pin 1, 2, 4, 5, 6 dan 7. Sesuai dengan library yang sudah dibuat oleh Bill Porter, koneksi pin-pin tersebut dengan board Arduino  (dapat dilihat pada kode program, pada baris ke 17) adalah sebagai berikut:

1. Pin 1 (Data) –> Pin Digital 12 Arduino
2. Pin 2 (Command) –> Pin Digital 11 Arduino
3. Pin 4 (Ground) –> Pin Ground Arduino
4. Pin 5 (Power 3.3V) –> Pin 3.3V Arduino
5. Pin 6 (Attention) –> Pin Digital 10 Arduino
6. Pin 7 (Clock) –> Pin Digital 13 Arduino

Untuk menghubungkan konektor PS2 dengan Arduino, anda membutuhkan jumper wires 1 pin dual-female, seperti yang ada di sini, dan jumper wires, seperti yang ada di sini. Berikut gambar jumper wires yang digunakan tersebut.

Jumper Wires 1 Pin Dual-Female

Jumper Wires

Pasang kabel jumper wires 1 pin pada konektor Wireless Receiver, hasilnya seperti pada gambar berikut.

Konektor wireless sudah dipasangkan jumper wires 1 pin

Biar gampang, kita pasangkan label di tiap-tiap kabel jumper, hasilnya seperti di bawah ini.

Konektor wireless dipasang jumper wires 1 pin dengan label

Kemudian kita hubungkan jumper wires tersebut dengan board Arduino (lihat kembali koneksi 6 pin konektor dengan board Arduino di bagian atas) , gunakan jumper wires yang dual-male. Hasilnya dapat dilihat pada gambar ini.

Konektor Wireless terhubung dengan Arduino Uno

Ok, setelah koneksi sudah terpasang, sekarang kita siap untuk mencoba koneksi wireless dengan PlayStation 2 Controller ini. Hubungkan kabel USB dari komputer ke boar Arduino. Buka IDE Arduino, siapkan Serial Monitor ( Ctrl+Shift+M) dan atur baud rate-nya pada posisi 57600. Kalau semua berjalan lancar, maka Serial Monitor akan menampilkan output dari tombol yang kita tekan pada Controller PS2. Tampilan pada Serial Monitor dapat dilihat pada gambar di bawah ini.

PS2 Wireless Controller Serial Monitor Output

Wow, kayaknya gampang ya…hmm gimana kalau kita coba untuk menggerakkan Servo. Ok, kode program di atas kita tambahkan beberapa baris kode untuk menggerakkan servo, kode lengkap dengan tambahannya dapat dilihat di bawah ini.
