Construction of a multimeter using the Arduino platform

U ovom završnom radu izgrađuje se multimetar pomoću Arduino platforme. Arduino je softverska i hardverska platforma koja korisniku nudi provedbu raznih projekata. To se postiže uz spajanje raznih električnih komponenti, senzora i aktuatora s mikrokontrolornom pločom te programiranjem njihovih funkcija na računalu. Ovdje se Arduino spaja i programira tako da mjeri napon i struju nekog strujnog kruga te nepoznati otpor i kapacitet. Dobivaju se poprilično točni rezultati, a neke greške se javljaju radi nedostatka elektroničkih komponenti te velikog dometa provjeravanih komponenti. Cilj rada je prikazati mogućnosti Arduino platforme. Arduino široj znanstvenoj zajednici nudi moćan instrument koji je dostupan po vrlo pristupačnoj cijeni i time je odličan za školstvo i edukaciju mnogih.In this bachelor thesis, a multimeter is built using the Arduino platform. Arduino is a software and hardware platform that offers users the implementation of various projects. This is achieved by connection of various electrical components, sensors and actuators to the microcontroller board and with programming their functions on the computer. Here the Arduino is connected and programmed to measure voltage and current of a circuit and the unknown resistance and capacitance. The results obtained are quite accurate, some error occur due to the lack of electronic components and a large range of the tested components. The aim of this thesis is to present the capabilities of the Arduino. The Arduino offers the wider scientific community a powerful instrument that is available at a very affordable price and thus is great for the schooling and education of many
