How to Control stepper motor using Microprocessor 8086 by assembly language program? As we all know that stepper motor driver plays an important role in automatic control system.We can create a stepper motor controller using 8086 microprocessor and 8255 Programmable Peripheral Interface IC. Here is the assembly language program for 8086 microprocessor.
This stepper motor assembly language program is quite simple and easy. Here we had described the functions of each code for better understanding.
Basically this assembly program is a beginner g ....etc

programming of atmega16 for traic

In this project, we will learn How to design a BT136 Triac based PC controlled home appliances system with AVR ATmega16 microcontroller Part-II. Here, we will use the PC keyboard as the input device to control the appliances i.e 2 bulbs and 2 fans and we will display the status of each appliance in the PC.

PC will send the control signal(ASCII value of pressed key value) to the ATmega16 microcontroller through its serial port. But current generation PCs and Laptops do not have serial port in them, so we will ....etc

Pulse-width modulation (PWM) can be implemented on the Arduino in several ways. This article explains simple PWM techniques, as well as how to use the PWM registers directly for more control over the duty cycle and frequency. This article focuses on the Arduino Diecimila and Duemilanove models, which use the ATmega168 or ATmega328.
If you're unfamiliar with Pulse Width Modulation, see the tutorial. Briefly, a PWM signal is a digital square wave, where the frequency is constant, but that fraction of the time the signal is on (the duty cycle) can ....etc
