Fanerva, Tisda Renza (2010) PEMBUATAN SISTEM KENDALI POSISI EKSPERIMEN LENSA MELALUI PORT SERIAL MENGGUNAKAN MOTOR LANGKAH. Undergraduate thesis, Department of Physics, Diponegoro University.
Now have been made control position system of lens experiment by serial port communication and stepper motor. These system contains of software and interfecing peripheral such us stepper motor, lens, stepper motor driver, and RS232. The software on microcontroller system use assembler programming and view of monitor interface use Delphi 7.0 language. These system use stepper motor which able to rotate eight degree for each step use fullstep methode. System motor connecting to sprocket to make moving of light source and lamp position. The rotating of stepper motor controlled by computer with stepper motor controlling program based on Delphi 7.0. Controlling of stepper motor use serial port interfacing from computer which current and voltage level have been convert by MAX232 to match with microcontroller and stepper motor driver. On interfacing of application view will get the distance of shadow and distance of object. Trial result show us that control system of lens experiment position have the distance of object y = (0,1623x + 17,426) cm, and it’s equal to 0,004 cm. And for the distance of shadow y = (0,1622x + 17,031) cm and it,s equal to 0,005 cm.
