Tentang Proyek Ini

Proyek ini akan memungkinkan Anda memanfaatkan kekuatan gerakan Anda untuk mengontrol LED RGB. Anda memerlukan Sparkfun APDS-9960 dan LED RGB COMMON CATHODE, bukan anode. Pastikan untuk menggunakan papan Arduino 5v dengan resistor 4.7k Ohm, karena sensor ini menggunakan protokol I2C. Kemudian sambungkan seperti dalam skematik. Dari sana Anda dapat menambahkan warna custom dalam kode. Saya telah menambahkan 6 warna. Kontrol default adalah: geser ke atas untuk menyala, geser ke bawah untuk mati, geser ke kanan untuk maju ke warna berikutnya, dan kiri untuk mundur. Kode ini dapat disesuaikan untuk berbagai jenis proyek lainnya! Silakan bereksperimen dan buat proyek yang lebih luar biasa. Happy making!
