Rancang Bangun Alat Penampung Buku Berbasis Arduino Pada Sistem Pengembalian Buku Layanan Mandiri

This study aims to design and create a book container in self-service return system at the Andalusia Library & Knowledge Center UPI "YPTK" Padang. Currently, is carried out through drop machine. designed complement The returned inserted into slanted gap so that it can slide container. When empty, base upper limit position. If entered, will automatically according thickness of book. And on, until full buzzer active. Thus, hoped damage be prevented due falling too far down. using ultrasonic sensors detect lower limits, DC motor move down After testing, works well able withstand loads up 22 kg with number books between 30 50 depending on size when load maximum. sensor book, limits activate full. this tool used support system.
