Mesin Penghalus Bumbu Otomatis Menggunakan Sensor Ultrasonik Berbasis Arduino Nano

Abstract

This study discusses ultrasonic sensors that work based on the principle of sound wave reflection and are used to detect the presence of a certain object in front of it,its working frequency is in the area above sound waves from 40 kHz to 400 kHz. This ultrasonic sensor consists of two units, namely a transmitter and a receiver unit that will working on the automatic spice grinder on this report.
