Tutorial ESP32: Game LEGEND ini bisa dibikin pake Arduino (Tetris) Oled Display + Joystick di WOKWI #game #tetris<\/strong><\/strong><\/p>\n\n\n\n

Pada bagian ini akan dibahas pembuatan proyek game legendaris Tetris berbasis mikrokontroler Arduino UNO, layar OLED Display SSD1306 0.96 inci (I2C), dan analog joystick<\/em> sebagai pengontrol pergerakan blok, serta software simulasi WOKWI. Skematik rangkaian ditunjukkan pada Gambar 1, program Arduino pada Kode 1, dan video pembuatan pada tautan Video 1. Pergerakan blok Tetris (rotasi, geser kiri\/kanan, dan drop<\/em>) diproses menggunakan pembacaan sinyal analog joystick. Layar OLED akan merender grafis blok secara real-time<\/em>, menghitung skor per baris yang berhasil dihancurkan, serta menampilkan kondisi game over<\/em> saat susunan blok telah mencapai batas atas.<\/p>\n\n\n\n
