Development of applications for school lab work based on bluetooth connection between smartphones and Arduino

Mobilne naprave bodo v prihodnosti postale nepogrešljiv pripomoček pri poučevanju. Razvoj novih mobilnih naprav se odvija zelo hitro in učenci imajo dostop do njih. Veliko časa preživijo pri njihovi uporabi in naloga učiteljev je, da poizkusimo ta čas preusmeriti na aplikacije, ki imajo poučno vsebino. V magistrskem delu opisujemo štiri aplikacije, ki smo jih izdelali za operacijski sistem Android. Za izdelavo aplikacij smo uporabili programsko opremo MIT app Inventor, pri kateri ni potrebno predhodno znanje računalniškega programiranja. Izdelava aplikacije poteka kot združevanje različnih komponent med seboj. Primeri aplikacij, temelječih na z bluetooth povezavi z elektronskim razvojnim okoljem Arduino, so prižiganje svetlečih diod, merjenje napetosti na potenciometru, krmiljenje kota zasuka servomotorja in merjenje razdalj z Arduino ultrazvočnim senzorjem. Pri vseh aplikacijah smo opisali tudi celotni postopek izdelave aplikacij. Aplikacije dvosmerno izmenjujejo informacije med mobilno napravo in krmilnikom Arduino. Vsako od aplikacij smo umestili v slovenski učni načrt in jo povezali z eksperimentom pri naravoslovnih predmetih in tehniki. S tem smo želeli slovenskim učiteljem dali možnost, da naredijo za mlade naravoslovne predmete in tehniko bolj priljubljeno s pomočjo uporabe novih tehnologij. Mobilne naprave, ki jih imajo učenci, bi tako lahko pedagoški delavci uporabili pri raznih šolskih projektih, zaključnih nalogah, raziskovalnih nalogah, tekmovanjih itd.In near future, mobile devices will become an indispensable accessories for teaching. The development of new devices takes place very quickly and all students have access to them. They spend a lot of their time using them, and the task of the teachers is to try to redirect them to using their devices for applications that have educational content. In my master\u27s thesis, I described four applications that we developed for the Android operating system. In order to create these applications, we used the MIT app Inventor software, which does not require prior knowledge of computer programming. The applications are designed with combining different components with each other. Examples of applications based on bluetooth connections with the Arduino electronic development environment are: the lighting of the LEDs, the measurement of the voltage on the potentiometer, the angle of rotation of the servo motor and the distance measurement with the Arduino ultrasonic sensor. We also described the entire application development proccess for all the applications. Applications have a two-way exchange system of information between the mobile device and the Arduino microcontroller. Each of the applications was placed in the Slovenian curriculum and connected it with an experiment in science subjects and in tehnology. With this, we wanted to give Slovenian teachers the opportunity to make science subjects and techniques more popular with young people by using new technologies. Student\u27s mobile devices could be used by pedagogical workers in various school projects, finishing tasks, research tasks, competitions, etc
