Razvoj avtomatskega sistema uglaševanja kitare : diplomska naloga visokošolskega strokovnega študijskega programa I. stopnje strojništvoŽerjav, Matej, 1991-Kitara je eden od najpogosteje uporabljenih glasbil. Za njeno pravilno delovanje je pomembno, da vsaka izmed šestih strun niha s točno določeno osnovno frekvenco. Procesu, kjer le to zagotavljamo, ... rečemo uglaševanje. Tudi že uglašene strune je potrebno po nekem času ponovno uglaševati, ker se z igranjem in drugimi zunanjimi vplivi strune razglasijo. V praksi pri uglaševanju pomagamo z univerzalnim uglaševalcem. Kljub temu pa se strune še vedno napenja ročno. Cilj zaključne naloge je izdelati avtomatski sistem uglaševanja kitare, pri katerem bi strune napenjal elektromotor. V ta namen smo uporabili mikrokrmilnik Arduino, ki preko mikrofona z ojačevalnim vezjem zaznava akustični signal. Na osnovi le tega določi frekvenco nihanja strune in jo primerja z zahtevano. Na osnovi odstopka pa nato s pomočjo koračnega elektromotorja ustrezno napne struno.Type of material - undergraduate thesis ; adult, seriousPublication and manufacture - Ljubljana : [M.
