Abstract

U ovom radu ćemo koristiti Arduino, model Leonardo, kako bi nam olakšao prikupljanje podataka tijekom izvođenja eksperimenta. Za prikupljanje podataka bit će nam potreban i nekakav senzor. Osim senzora potrebno je i napisati program na Arduinu koji će mu dati do znanja koje podatke da prikupi, koliko često da ih prikuplja te gdje i kad da ih šalje kad ih je prikupio. Na drugom kraju, kad smo te podatke primili, trebamo nešto s njima i napraviti. Za to nam služi računalo na kojem ćemo napisati program da dobivene podatke prikupi, obradi i prikaže u grafičkom sučelju te kad smo gotovi s eksperimentom obrađene podatke spremi u trajnu memoriju. U našem slučaju odlučili smo se usredotočiti na ultrazvučni senzor pomoću kojeg ćemo mjeriti udaljenost. Mjerenje udaljenosti ćemo iskoristiti kako bi promatrali gibanje utega, prvo kao njihanje na opruzi, a zatim kao osciliranje na niti. Razlog zašto smo se odlučili za ovakav izbor senzora i eksperimenta jest jednostavnija kontrola varijabli koja će nam omogućiti bolji pregled mogućnosti samog Arduina i njegovih granica. Tijekom provođenja eksperimenta također ćemo pripaziti na njegovu izvedivost u učionici unutar okvira nastavnog sata i na razumljiv prikaz sadržaja učenicima. Iz tog je razloga također titranje optimalan izbor.

Abstract (english)

In this thesis we will be using the Arduino, model Leonardo, to facilitate the gathering of data during our experiment. To gather the data we will also be needing a sensor. It is also necessary to write a program on the Arduino to specify which data needs to be collected, how often it needs to be collected and where and when to send the data once it has been gathered. On the other end, once we've received our data, we need to do something with it. For that purpose we are using a computer on which we will write a program to gather, process and present the data in a graphical user interface. Once the experiment has been finished the program will store the processed data in the computers' permanent memory. In our case we decided to focus on the ultrasonic sensor with which we will be measuring distance. The distance measurement will be used to observe the movement of a weight, first as oscillations on a spring, and afterwards as swinging on a thread. The reason we opted for this particular choice of sensor and experiment is the ease of variable control which will give us a better overview of the Arduinos' possibilities and its limitations. During the experiment we will pay attention to the experiments' feasibility in the classroom during a lesson and to the understandable display of the content to the students. For that reason as well oscillations are the optimal choice.
