Abstract
Uvijek prisutna želja za napretkom zastupljena je u svim sferama djelovanja čovjeka, osobito kad je u pitanju ispitivanje granica sposobnosti ljudskog tijela. U ovom je radu projektiran i izrađen prototip elektroničkog uređaja čija je svrha mjerenje vremena reakcije na zvučne podražaje. Detekcija reakcije vrši se pomoću inercijske mjerne jedinice (engl. Inertial Measurement Unit, IMU) koja se sastoji od akcelerometra (za mjerenje akceleracije u tri koordinatne osi x, y i z), žiroskopa (za mjerenje brzine zakreta u tri osi) te opcionalno magnetometra (za mjerenje gustoće magnetskog polja Zemlje u tri osi). Korištenjem komercijalno dostupne inercijske jedinice tipa MPU6050 moguće je detektirati gibanje, odosno trzaj. Ta je značajka iskorištena za izradu prototipa koji se temelji na NodeMCU V3 mikrokotroleru. Rezultati detekcije se putem WiFi komunikacije i generiranja web stranice prikazuju na povezanom računalu ili mobilnom telefonu. Programski kod prototipa napisan je u Arduino IDE okruženju. Za navedeni prototip, izrađeno je kućište tehnologijom 3D printanja dizajnirano u SolidWorks programskom paketu. Pomoću platforme Altium Designer projektirana je tiskana pločica koja integrira mikroprocesor korištenog mikrokontrolera i inercijsku jedinicu integriranu u senzorskom modulu korištenom pri izradi prototipa. Ispitivanje uređaja realizirano je montažom na vreću za boks pomoću elastičnih podesivih traka i testiranjem funkcionalnosti.
Abstract (english)
The ever-present desire for progress is represented in all forms of human activity, especially when it comes to testing the limits of the human body. An electronic device to measure reaction time to sound stimuli was described, developed, and build in this final paper. Reaction detection is realized with the help of an Inertial Measurement Unit (IMU), which consists of an accelerometer (for measuring acceleration in three coordinate axes x, y, and z), a gyroscope (for measuring angular velocity in three axes), and optionally a magnetometer (for measuring Earth's magnetic field in three axes). By using a commercially available MPU6050 type inertial measurement unit, a prototype with the ability to detect movement was developed. The prototype is based on the NodeMCU V3 microcontroller which enables the display of detection results on a connected computer or mobile phone via WiFi communication and web page generation. The code of the prototype was written using the Arduino IDE environment. For the prototype, an enclosure has been designed using the SolidWorks software package and created using 3D printing technology. A printed circuit board was designed using the platform Altium Designer. The PCB integrates the microprocessor of the microcontroller and the inertial unit of the sensor module used to build the prototype. The device testing has been conducted by mounting it on a punching bag using elastic adjustable bands in order to check functionality.
