Tentang proyek ini
Proyek ini menggabungkan 3 matriks LED RGB 8x8 WS2812B dan sensor gerak PIR untuk menyambut pengunjung dengan teks yang mengatakan “Happy Holidays & Happy New Year!” saat mereka cukup dekat dengan pintu dan menampilkan serangkaian efek seperti layar menyala pada monitor saat sensor tidak mendeteksi siapa pun di dekatnya.
Dikontrol oleh Arduino UNO dan diberi daya oleh sumber daya 5v 30a.
Saya menggabungkan atau menggabungkan 3 rangkaian kode.
Yang dari DemoReel100 Contoh Library FastLED untuk Efek Idle/Standby.
Kode Sensor Gerak PIR
Dan kode setup untuk Neopixel, saya pikir. Saya tidak benar-benar yakin lagi, tbh,, karena itu hampir sebulan yang lalu saat saya menggabungkan kode bersama.
Saya juga menggunakan sensor gerak PIR lain yang terhubung ke Relay 5v dengan Chayat LED RGB 12v melalui kabel senggak dan dikontrol oleh Arduino Nano.
String LED, bersama dengan lampu liburan yang juga terhubung ke kabel senggak diaktifkan saat sensor PIR pertama mendeteksi gerakan. Ini terletak di langit-langkat dekat tangga pertama.
Setelah beberapa langkah naik, sensor PIR kedua memberi tahu UNO untuk menampilkan Teks pada matriks ketika seseorang cukup dekat ke pintu.
