STEPPER MOTOR INTERFACE USING 8085 MICROPROCESSOR AIM: The butt glass of the project is to demonstrate the onwards/reverse stepped interrogatives of a hoofer go, use 8085 microprocessor. PROJECT DESCRIPTION: The stepping motor motors extradite considerable applications in printing, Industrial Robotics, Precision tool motions in drilling, shimmy and shaping machines, lathe etc. This project is proposed to demonstrate interfacing of stepper motor to 8085 microprocessor and to crop it in continuous or stepped motion in forward or reverse direction at a lower place program control, using 8085 microprocessor. HARDWARE DESCRIPTION: The hardw are apparatus consists of a microprocessor motherboard and stepper motor interface board. The motherboard consists of 8085 MPU, 8KB EPROM, 8KB RAM, Keyboard and display ascendence 8279, 21-key Hex-keypad and six come of seven segment LEDs and Bus enlargement connector. The stepper motor interfac e consists of moilr junction transistors for stepper motor windings and squall decipher circuit. The microprocessor output the binary date through selective information private instructor, which are converted to current pulses by the driver transistors and use to drive stepper motor. The software for the system is developed in 8085 multitude language.
