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

elevator implementation using 8086 and 8255

The 8086(eighty eighty-six, also called iAPX 86)is a 16-bit microprocessor chip designed by Intel between early 1976 and mid-1978, when it was released. The Intel 8088, released in 1979, was a slightly modified chip with an external 8-bit data bus (allowing the use of cheaper and fewer supporting ICs), and is notable as the processor used in the original IBM PC design, including the widespread version called IBM PC XT.The 8086 gave rise to the x86 architecture which eventually became Intel' ....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

automatic railway gate controller using stepper motor ppt

ABSTRACT

This project work aims at the design, development, fabrication and testing of working model entitled Automatic Railway Gate Controller. It is basically related to Radio communication and signalling system. An Automatic Railway gate controller is unique in which the railway gate is closed and opened or operated by the Train itself by eliminating the chances of human errors.The largest public sector in India is the Railways. The network of Indian Railways covering the length and ....etc
