Skematik rangkaian ditunjukkan pada Gambar 1, program Arduino pada Kode 1, dan video pembuatan pada tautan Video 1. Sistem memantau kuota ketersediaan slot parkir (kapasitas 10 slot) secara otomatis melalui pergerakan kendaraan yang masuk dan keluar. Ketika kendaraan terdeteksi di gerbang masuk dan slot masih tersedia, palang pintu masuk akan terbuka dan mengurangi jumlah sisa slot secara otomatis setelah kendaraan lewat. Sebaliknya, saat kendaraan keluar melalui gerbang keluar, palang pintu keluar akan terbuka dan menambah kembali jumlah slot yang tersedia. Jika kapasitas parkir telah habis (STATUS: PENUH), sistem secara otomatis mengunci palang pintu masuk dan menyalakan LED indikator.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><a href=\"https:\/\/www.youtube.com\/watch?v=6TwozmBA4Uw&amp;lc=UgxDHpB3c7dSAbortGZ4AaABAg\" target=\"_blank\" rel=\"noreferrer noopener\"><img decoding=\"async\" loading=\"lazy\" width=\"1024\" height=\"714\" src=\"https:\/\/kuliahelektro.org\/wp-content\/uploads\/2026\/10\/image-1024x714.png\" alt=\"\" class=\"wp-image-499\" srcset=\"https:\/\/kuliahelektro.org\/wp-content\/uploads\/2026\/10\/image-1024x714.png 1024w, https:\/\/kuliahelektro.org\/wp-content\/uploads\/2026\/10\/image-300x209.png 300w, https:\/\/kuliahelektro.org\/wp-content\/uploads\/2026\/10\/image-768x535.png 768w, https:\/\/kuliahelektro.org\/wp-content\/uploads\/2026\/10\/image.png 1281w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><\/a><\/figure>\n\n\n\n<p class=\"has-text-align-center\"><strong>Gambar 1.
