Mengendalikan LED Menggunakan Remote Infrared dan Arduino

Skema & Diagram Sirkuit

Skema Rangkaian LED dengan Remote Infrared

Rangkaian menggunakan Arduino UNO, sensor infrared TSOP1738, remote IR, dan tiga kelompok LED dengan warna berbeda.

Koneksi Sensor TSOP1738

• OUT: pin digital 9 Arduino UNO.
• GND: GND Arduino UNO.
• VCC: 5V Arduino UNO.

Koneksi LED

• LED Merah: empat LED dengan anoda terhubung ke pin digital 6 melalui resistor pembatas arus.
• LED Kuning: empat LED dengan anoda terhubung ke pin digital 7 melalui resistor pembatas arus.
• LED Biru: empat LED dengan anoda terhubung ke pin digital 8 melalui resistor pembatas arus.
• Katoda seluruh LED: terhubung ke GND Arduino UNO.

Arduino membaca sinyal dari remote melalui TSOP1738. Setelah kode tombol dikenali, Arduino mengendalikan kelompok LED melalui pin digital 6, 7, dan 8.

Catatan: Pada bagian Hookup, dokumentasi menyebut pin 9 sebagai OUT TSOP1738. Bagian Code juga menggunakan RECV_PIN = 9. Diagram skematik digunakan sebagai referensi visual untuk perakitan.

Catatan teknis: Kode di atas mempertahankan struktur dan perintah dari sumber asli. Ada beberapa bagian yang perlu diperiksa sebelum digunakan: pin 5 dipakai pada salah satu pola tambahan tetapi tidak didefinisikan sebagai output pada setup(); fungsi random(0.2, 2 + 1) menggunakan argumen desimal yang akan dikonversi menjadi integer; dan penamaan proyek sebagai LED Strip tidak sama dengan daftar hardware yang sebenarnya mencantumkan 12 LED terpisah dalam tiga kelompok warna. Library IRremote versi terbaru juga mungkin memerlukan penyesuaian API.
