Arduino Tetris by Sanchen ID
Membuat Game Tetris Sederhana Menggunakan Arduino Nano
Pendahuluan
Arduino Nano merupakan salah satu papan mikrokontroler yang banyak digunakan dalam proyek elektronika dan pembelajaran pemrograman karena ukurannya yang kecil, harga terjangkau, serta kemampuannya yang cukup mumpuni. Salah satu proyek menarik yang dapat dikembangkan menggunakan Arduino Nano adalah pembuatan game Tetris sederhana.
Game Tetris dipilih karena memiliki konsep logika yang jelas, melatih pemahaman pemrograman, serta dapat dikombinasikan dengan komponen hardware seperti layar LED, LCD, atau OLED. Proyek ini sangat cocok untuk pelajar, mahasiswa, maupun pemula yang ingin belajar pemrograman Arduino dengan cara yang menyenangkan.
Konsep Game Tetris pada Arduino
Tetris adalah permainan menyusun balok dengan berbagai bentuk (tetromino) yang jatuh dari atas layar. Pemain harus memutar dan menggeser balok agar tersusun rapi. Jika satu baris penuh, baris tersebut akan menghilang dan skor bertambah.
Dalam versi Arduino Nano, konsep ini disederhanakan agar sesuai dengan keterbatasan memori dan kecepatan mikrokontroler. Tampilan game biasanya ditampilkan menggunakan:
LED Matrix
LCD 16x2
OLED Display
Kontrol permainan dapat menggunakan beberapa tombol seperti tombol kiri, kanan, rotasi, dan jatuh cepat.
Cara Kerja Program Arduino Tetris
Program Arduino Tetris bekerja dengan beberapa tahapan utama:
Inisialisasi Sistem
Pada awal program, Arduino akan menginisialisasi layar, tombol input, serta variabel penting seperti skor dan posisi balok.
Pembentukan Balok (Tetromino)
Setiap balok direpresentasikan dalam bentuk array atau matriks kecil. Arduino akan memilih balok secara acak dan menampilkannya di bagian atas layar.
Pergerakan Balok
Balok akan bergerak turun secara otomatis berdasarkan waktu (delay). Tombol input memungkinkan pemain menggeser atau memutar balok.
Deteksi Tabrakan
Program akan memeriksa apakah balok menyentuh bagian bawah layar atau balok lain. Jika iya, balok akan dikunci di posisi tersebut.
Penghapusan Baris
Jika satu baris terisi penuh, baris tersebut akan dihapus dan skor pemain bertambah.
Game Over
Permainan akan berakhir jika balok tidak dapat lagi ditempatkan di area permainan.
Manfaat Mempelajari Proyek Ini
Membuat game Tetris menggunakan Arduino Nano memberikan banyak manfaat, antara lain:
Melatih logika pemrograman dan algoritma
Memahami penggunaan array dan kondisi (if-else)
Belajar mengelola input dan output perangkat keras
Mengembangkan kreativitas dalam proyek mikrokontroler
Proyek ini juga dapat dikembangkan lebih lanjut, seperti menambahkan suara buzzer, sistem level, atau penyimpanan skor tertinggi.
