Abstract

Na početku ovog rada su navedeni odgojno-obrazovni ishodi iz kurikuluma nastavnog predmeta Informatike za domenu Računalno razmišljanje i programiranje za osnovnu i srednju školu koji su povezani s korištenjem mikrokontrolera i senzora, odnosno robota. Zatim su uspoređeni programski jezici Logo i Scratch te je opisan senzor objekata pod imenom Pixy. Također je opisan pomoćni program PixyMon koji omogućuje prikaz objekata koje ovaj senzor prepoznaje. Objašnjen je način definiranja jednostavnih potpisa (signatures) i kodiranja bojom (color codes). Opisane su naredbe iz ekstenzije PixyCAM I2C za rad s Pixyjem u mBlocku. Obrađene su dvije aktivnosti prikladne za učenike sedmih razreda osnovne škole i opisani određeni problemi prilikom korištenja naredbi iz ekstenzije PixyCAM I2C te dane sugestije za njihovo rješavanje. U radu je opisano i programsko okruženje Arduino IDE s naglaskom na naredbe za rad s Pixyjem. Opisan je primjer osnovnog programa napisanog u Arduino IDE koji na serijski monitor ispisuje podatke o detektiranim objektima. Na kraju rada je opisan složeniji program za praćenje objekata za edukacijski robot opremljen kamerom Pixy.

Abstract (english)

At the beginning of this work, the learning outcomes from curriculum of the Informatics for domain "Computer Thinking and Programming" for Elementary and Secondary Schools that are related to the use of microcontrollers, sensors and robots are analised. After that, the programming languages Logo and Scratch are compared, and a sensor of objects named Pixy is described, together with PixyMon, utility for presenting what objects this sensor detects. The way of defining signatures and color codes is explained in detail. Commands from the PixyCAM I2C Extension for Pixy Operation in mBlock are described. Two activities suitable for seventh grade students are presented. Some problems that are encountered while using the PixyCAM I2C extension are pointed out and suggestions for solving them are proposed. In the last part of this work, the Arduino IDE programming environment is described, emphasising commands for working with Pixy. An example of the basic program written in Arduino IDE which sends data about detected objects to the serial monitor is presented. At the very end of this work, a more complex program for monitoring objects by educational robot equipped with the camera Pixy was described.
