(Politeknik Negeri Batam, 2017-09-23) Anugrah Aghasti, Agung; Analia, Riska
Music is tone, rhythm, melody and symphony which arranged until be a music especially from the sound that produced by soundable things. The most popular music instrument is guitar. Before we play guitar we have to take a look at how we set the string up, because it fluencing to the music we play and need long time to set the string up. So from the problem above we need a device to tune the guitar's string automatically to help the musician who have problem about tuning guitar's string. But before we build it we need the frequency literature from each guitar's string to help the research. This research using microcontroller as a master to initialization the frequency by doing thresholding events at the string signal which amplified by operational amplifier to assist initialization string's frequency which use microcontroller as slave to be a frequency reciever which initialized by master and move the servo motor to appropriate the string to basic frequency. Sending data frequency between master and slave this final project using bluetooth. from this research data produced above have 0,3 until 1 Hz difference, and need about 16 until 20 second to tune the guitar.
