Abstract
Izhodišče za pripravo diplomskega dela predstavljata načrtovanje in izdelava prilagoditvenega vezja za krmiljenje oziroma regulacijo laboratorijskih naprav prek mikrokrmilniške tiskanine Arduino Uno oziroma katerekoli naprave, zmožne oddajanja t. i. pulzno širinskega modeliranega signala (angl. pulse-width modulation). Razloženo bo, kako je mogoče s pomočjo osnovnega teoretičnega znanja o električnih elementih (kot so na primer operacijski ojačevalnik, tranzistor, dioda, kondenzator, upori itd.) sestaviti delujočo shemo oziroma električno vezje za zgoraj omenjeni namen. Opisan bo celoten postopek od idejne zasnove do praktične izdelave naprave. Prve zamisli bodo najprej simulirane v računalniškem okolju, sledilo pa bo dejansko testiranje na preizkusni ploščici ali t. i. protoboardu. Dosegu optimalnega delovanja na protoboardu sledi načrtovanje vezja v namenskem računalniškem programu, kjer moramo biti pazljivi na položaj posameznih elementov glede na njihovo praktično uporabo in morebiten medsebojni vpliv. Sledijo izdelava vezij s pomočjo t. i. fotopostopka ter končna postavitev in montaža v ohišje z vsemi pripadajočimi sponkami, stikali in gumbi.

Title:Design of a matching circuit for laboratory pilot plants control using a microcontroller
Abstract:
The basis for the preparation of the thesis represent the planning and production of the adaptive circuit for controlling or regulation of laboratory devices through the Arduino Uno microcontroller board or any other device, capable to transmit a so called Pulse-width modulation signal (PWM). Explained will be how it is possible to assemble a working scheme or electric circuit with the help of basic theoretical knowledge on electrical elements (e.g. operational amplifier, transistor, diode, capacitor, resistance etc.) for the stated purpose. Describer will be the entire process from the idea to the practical manufacture of the device. The initial ideas will be simulated in the computer environment, followed by actual testing on the protoboard. Reaching of the optimal functioning on the protoboard will be followed by planning of the circuit in proper software, where we must take care of the position of individual elements regarding their practical use and mutual influence. This is followed by the manufacture of circuits with the help of the photoprocedure; the final placement and assembly into the housing with all the with all the associated clips, switches and buttons.

Keywords:controlling, regulation, PWM, Arduino UNO, LT SPICE, EAGLE, operational amplifier, H-bridge
