GPS cycle computer

This article is dedicated to the realization of a GPS cycle computer, of which modules is composed and connected. The first section devoted to realization of GPS cycle computer basing on Arduino Mega 250 microcontroller. In the second section, it deals with the description of program functions which will test and compare with selected parameters of a GPS computer. In the third section, the article describes creation of a bicycle wheel model, the parts of which is built and how these parts work. Finally, it describes the design of the bicycle wheel model and the testing and comparison of the parameters. At the end, the test parameters are compared. It was found that the measured parameters between the stepper motor and the magnetic sensor were identical, but there was a difference between the engine and the GPS cycle engine.
