👂🏼 👩🏽‍🚒 💨 Riasan untuk cyber Cinderella. Proyek akhir pekan Arduino. Bulu mata yang dipimpin 😩 🐃 🔱

Untuk pertama kalinya, bulu mata LED ditunjukkan oleh desainer Tien Pham di The Maker Faire di San Francisco. Itu dua tahun lalu. Yah, dan hampir segera di gua Alibaba, perampok Cina mulai mendistribusikan analog untuk 400 atau bahkan 300 rubel.

Dalam gambar, ini adalah dua papan sirkuit cetak tipis dengan dua belas LED yang dihubungkan dengan kabel tipis ke papan kontrol dengan baterai. Bulu mata bercahaya dipasang menggunakan lem khusus di atas biasa atau salah, dan controller dan baterai tersembunyi di rambut. Secara teknis, pada pandangan pertama, tidak ada yang rumit. Tapi! Jika Anda melihat dari dekat ke papan bulu mata ada 12 LED, dan hanya ada tiga kabel di loop. Pada saat yang sama, LED tidak hanya menyala atau berkedip, tetapi juga berfungsi seperti lampu berjalan. Saya bertanya-tanya setengah hari bagaimana mereka melakukannya. Revisi banyak iklan. Dan, dalam gerakan lambat, ternyata LED melakukan efek berpasangan. Artinya, tugas itu segera dipersempit untuk mengontrol enam LED pada tiga kabel. Tapi tetap saja, tiga! Enam dalam tiga! Sekali lagi - enam dalam tiga. Dan lagi ... Kemudian dia mengulangi lagi dan jawabannya entah bagaimana muncul dengan sendirinya. Ini dia - jumlah semua permutasi dari tiga elemen adalah 6!

Ternyata mikrokontroler mengurutkan tiga sinyal pada loop yang terdiri dari tiga konduktor: nol, satu, dan keadaan ketiga. Kami mendapatkan enam kombinasi / permutasi, yang berarti bahwa pada setiap permutasi salah satu dari enam LED menyala. Jika mereka termasuk dalam skema ini:

Misalnya, nyalakan LED D2. Pada A-nol, pada B - status ketiga, pada unit-C. Hanya LED D2 yang menyala!

Sekarang Nol dan satu di output mikrokontroler mudah. Dan negara ketiga? Lebih mudah lagi. Atur mode input. Sekarang input impedansi tinggi, yang tidak ditarik ke nol atau satu, praktis terputus dari sirkuit kontrol.

Selanjutnya adalah kode, yang secara dinamis mengendalikan output mikrokontroler, nyalakan sejumlah LED. Kami membuat lampu berjalan, berkedip, berkilau, padam pada akhirnya.
Di bawah ini adalah kode untuk Arduino dengan beberapa efek untuk dua bulu mata dengan masing-masing enam kelompok LED.

Dan gadis ini Veronica menunjukkan efek ini.

Mungkin, bagi sebagian orang metode manajemen ini sudah lama dikenal dan Anda sudah menggunakannya. Tapi bagaimanapun juga, benar-benar ingin berbagi. Arduin harus menyukainya!
