RANCANG BANGUN ALAT UKUR KECEPATAN GERAK REFLEK MENGGUNAKAN MIKROKONTROLER AT89S51 DIANTARMUKAKAN KOMPUTER

Abstract

Have been done a making design to wake up the measuring instrument move of reflect use microcontroler AT89S51. This system can delivered data to computer with serial communications. This peripheral applicable to measure the speed move of human reflect being, and can be used in so many need, for example measuring speed move of athlete reflect, knowing the condition of someone health and others. This system use hardware 4 Relay, 4 lamp, 4 saklar, Max RS232 and microcontroler AT89S51. Relay have function to control lamp, Max RS232 for the communications of serial between microcontroler with the computer. Application program of computer use the program of Borland Delphi 7.0 to sending and accepting serial data at mikrokontroler AT89S51. On the program of Borland Delphi 7.0 data serial sent to microcontroler, and then activate the process of count timer and also control the relay and lamp. Relay and lamp controlled by microcontroler AT89S51 with the data input from saklar. Saklar deliver data to microcontroler and then by microcontroler will be processed,if corret so mikrokontroler will discontinue the process of the counting timer. From research done to be by result of measurement of time count move the reflek. measurement of time Count move the reflek a set of milisekon. Data of time Count move the reflek can be noted and presented. At this system, data in computer will save in microsoft excel
