Abstract
Arduinom generirane frekvencije od 10000 Hz do 500000 Hz (s korakom koji u početku kreće od oko 10000 Hz, povećava se s porastom frekvencija (postaje „grublji“) te se pri visokim frekvencijama korak produljuje i to 30000 Hz) koje su željene na ulazu u sklop moraju se dobiti dijeljenjem frekvencije od 16000000 Hz s potrebnim brojem kako bismo dobili željenu frekvenciju uzimajući u obzir da je Duty Cycle 50%, odnosno da u pravokutnom signalu jednako traju high i low ( logička ‘1’ i ‘0’ ) stanje, stoga moramo frekvenciju još podijeliti s 2. Programobilan mikrokontroler je programiran u “Arduino IDE” programu na način da za zadane frekvencije mjeri napon na sklopu i vrti tu petlju sve dok ne dođe do zadnje frekvencije. U zadnjem dijelu programa odabire se najpovoljnija frekvencija, tj. ona koja najviše utječe na promjenu napona.
Abstract (english)
The Arduin generated frequencies from 10000 Hz to 500000 with a step of 10000 Hz, which are required at the input of the circuit must be obtained by division of frequency of 16000000 Hz with the required number so we can get wanted frequency. We have to pay attention that Duty Cycle is 50%. It means that in the rectangular signal both the high and the low signal state are equal (logical ‘1’ and ‘0’), so we have to divide frequency with 2. The programmable microcontroller is programmed in the “Arduino IDE” program by measuring the voltage in the circuit for the default frequencies and rotetes that loop until the last frequency is reached. The last part of the program selects the most favorable frequncy, actually, the one that most influences the voltage change.
