stepper motor interfacing with 8085 using 8255 pdf

A stepper motor is a digital motor. It can be driven by digital signal. Fig. shows the typical 2 phase motor rated 12V /0.67 A/ph interfaced with the 8085 microprocessor system using 8255. Motor shown in the circuit has two phases, with center-tap winding. The center taps of these windings are connected to the 12V supply. Due to this, motor can be excited by grounding four terminals of the two windings. Motor can be rotated in steps by giving proper excitation sequence to these windings. The l ....etc

A stepper motor is stepped from one position to the next by changing the currents through the fields in the motor. The two common field connections are referred to as two phase or four phase. There are three main areas of applications for stepper motor. i. Instrumentation ii. Computer peripherals ii. Machine drives.They are used in floppy drives, dot-matrix printers, X-Y plotters, digital watches
etc to rotate things in steps of small angles. The step size in typical stepper motor varies from .

This AVR tutorial will discuss interfacing Light Emitting Diodes with Atmel's AVR series of Microcontrollers. A LED is an acronym for Light Emitting Diode and is basically a electronic device which emits light when an electric current flows through it. The electronic symbol for a LED is : LED Symbol

General purpose LEDs used in digital circuits require around 75mA or less and so we usually use resistors to limit the current flowing through the LED when it is connected within a circuit as shown below. The resistance of the resistor is calcula ....etc

Introduction:

A stepper motor (or step motor) is a brushless, synchronous electric motor that can divide a full rotation into a large number of steps.
Stepper motors are similar to switched reluctance motors (which are very large stepping motors with a reduced pole count, and generally are closed-loop commutated.)

Fundamentals of operation

Stepper motors operate differently from DC brush motors, which rotate when voltage ....etc

Abstract:
This project focuses on developing an embedded system to control the operation of the stepper motor using micro controller. It consists of two parts; one is transmitter which consists of pc, level converter, microcontroller, RF transmitter. Another one is receiver which consists of RF receiver, microcontroller, stepper motor and stepper motor driver.
If we want to control the motor the information is given to the microcontroller using pc. Microcontroller recognizes the data and provides the appropriate information to the RF t ....etc
