MEMBUAT RANGKAIAN LAMPU STROBO DENGAN ARDUINO

Dalam pembelajaran informatika kelas 12, siswa tidak hanya diajak memahami teori pemrograman, tetapi juga bagaimana ilmu tersebut dapat diterapkan secara nyata dalam kehidupan sehari-hari. Salah satu proyek sederhana namun menarik adalah membuat lampu strobo menggunakan Arduino Uno.

Proyek ini memanfaatkan papan mikrokontroler Arduino Uno yang diprogram untuk mengatur nyala dan padam LED dengan kecepatan tertentu sehingga menghasilkan efek cahaya strobo, mirip dengan yang sering digunakan pada pertunjukan musik atau pencahayaan khusus. Dengan menyusun rangkaian sederhana—menghubungkan LED, dan kabel jumper—serta menuliskan kode program di Arduino IDE, siswa dapat langsung melihat hasil kerjanya dalam bentuk lampu yang berkedip cepat.

Melalui kegiatan ini, siswa belajar menghubungkan logika pemrograman dengan perangkat keras, sekaligus melatih kreativitas dalam merancang variasi kedipan, kecepatan, maupun pola cahaya. Proyek lampu strobo bukan hanya seru untuk dicoba, tetapi juga membuka wawasan siswa tentang bagaimana teknologi embedded system bekerja di dunia nyata.
