Skematik rangkaian ditunjukkan pada Gambar 1, program Arduino pada Kode 1, dan video pembuatan pada tautan Video 1. Sistem mengukur jarak objek dengan memanfaatkan prinsip pantulan gelombang suara ultrasonik. Program mengirimkan pulsa trigger selama 10 mikrosekon, kemudian membaca durasi waktu pantulan gelombang pada pin echo menggunakan fungsi pulseIn(). Hasil pembacaan durasi dikonversi menjadi satuan centimeter (cm) menggunakan rumus kecepatan suara dan ditampilkan secara real-time melalui Serial Monitor Arduino IDE.<\/p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full is-resized\"><a href=\"https:\/\/www.youtube.com\/watch?v=AanFaR-rA3w&amp;lc=Ugz-fmeurqg3_9WtNPd4AaABAg\" target=\"_blank\" rel=\"noreferrer noopener\"><img decoding=\"async\" loading=\"lazy\" width=\"720\" height=\"647\" src=\"https:\/\/kuliahelektro.org\/wp-content\/uploads\/2026\/11\/image-19.png\" alt=\"\" class=\"wp-image-660\" style=\"aspect-ratio:1.1128284389489953;width:462px;height:auto\" srcset=\"https:\/\/kuliahelektro.org\/wp-content\/uploads\/2026\/11\/image-19.png 720w, https:\/\/kuliahelektro.org\/wp-content\/uploads\/2026\/11\/image-19-300x270.png 300w\" sizes=\"(max-width: 720px) 100vw, 720px\" \/><\/a><\/figure><\/div>\n\n\n<p class=\"has-text-align-center\"><strong>Gambar 1.
