3d drawing program which processes sensor voltage ratings ınstantly from parallel port

Abstract

In this study, it is aimed to form 3D graph of any analog data changing related to its position, in computer environment instantly. For that purpose, a new 3D drawing program which updates itself by getting data instantly from an open txt file is developed. The analog data saved in a txt file is provided by KMZ51 AMR sensor that shows voltage changing according to the size of magnetic flux. That is why, output ends of the sensor are put into the Analog Digital Converter (ADC) which has got 24 bit resolution and the output of ADC is connected to the parallel port of the computer. The command that sends voltage in the sensor to the computer is given by the user via a trigger button connected to the parallel port. Every time the user pushes the button, the voltage value which is measured in the sensor comes to the computer as digital data, later on, the analog equivalent of the digital data is found and it is recorded in a txt file. This newly developed 3D drawing program’s database is constituted by this file. In this paper, developed 3D drawing program’s usage and operation are discussed in detail.
