DC Motor Speed Control System In The Rhythm Of Angklung Musical Instrument

Abstract

Technological developments to help and facilitate humans are robots. Robots can also be used to introduce or preserve new traditional arts with a modern twist that the younger generation can accept, one of which is the angklung robot. The authors designed an angklung robot control system to introduce and preserve the technology-based angklung musical instrument. The angklung robot combines traditional musical instruments with robot control that works automatically based on the input song and consists of other components. The components used in the angklung robot include the Max4466 sensor, the Arduino Mega2560 microcontroller, the relay module, and the DC motor. The working system of the angklung robot connects a computer to the angklung robot via a USB cable. After that, entering the song is read by the sound sensor, processed by the Arduino Mega2560, controlled by the PID method, and produced output to the DC motor up to the Angklung. Several experiments were taken for the success of the angklung robot tool from the speed of the motor and the investigation of the sound of the song with satisfactory results. The results of proper sensor testing are obtained for each analog value, Tone Do has a frequency of 352 Hz, Tone Re has a frequency of 431 Hz, Tone Mi has a frequency of 565 Hz, Tone Fa has a frequency of 632 Hz, Tone Sol has a frequency of 712 Hz, Tone La has a frequency 792 Hz, the Si tone has a frequency of 853 Hz and the Do' tone has a frequency of 912 Hz. Taken my balloon song experiment five times with a slight difference in analog value but still producing an angklung rhythm that matches my balloon song. There are five of them.
