Introduction This project demonstrates an AVR based DC Motor Controller using the ATmega16 microcontroller in Proteus simulation. It is a simple but useful microcontroller project for learning how PWM can control the speed of a DC motor. The circuit uses the ATmega16 to generate a PWM signal and drive a motor through a transistor-based motor […]

This tutorial is about how to use interrupt in AVR Atmega32A microcontroller. Interrupt enhances a use of microcontroller in many different ways. Interrupt is exactly the same as it means in English. Normally we expect a program to keep on executing sequentially in the way we have defined. When interrupt occurs the normal flow of instruction is

A modern microcontroller has almost everything that’s needed to implement a touch sensor matrix. There are several sensing technologies: IC manufacturers typically advise using certain tech, sometimes they offer ready to use hardware- or software-based solutions. I was curious to try to implement a sensor matrix entirely from scratch all by myself. Here’s how it

The Arduino is a very cool development board where you could create hundreds of projects. But it doesn’t mean that for every project you create, you would need an Arduino board dedicated to that project alone. A hundred projects and a hundred Arduinos? That’s a waste of money! Depending upon the requirements of your project,

This projects uses 8MByte SDRAM from a 168 pin DIMM SDRAM and generates videosignal for a VGA monitor with a resolution of 512×480 pixels with 256 colors at 60Hz using mega8515. The project uses burst mode of SDRAM, which can feed up to 512 bytes without MCU help. This means that MCU can do anything

Low power consumption Better Amperes display resolution while using low value drop resistor. Much smaller PCB size, only 5cm x 5cm. Still no SMD components. Easy calibration, only one voltage adjust and one ampere adjust preset, no voltage out detection. Voltage supplied by my 12Volt benchtop PSU(The resistor at output terminal is disconnected. The 10Ohm

Timers are widely used in industrial and domestic application for automating tasks. Microcontrollers can be used to design versatile and accurate timers with ease. Here I present a simple timer that can be used to turn on/off a load after user specified time. The Timer uses a standard 16×2 lcd module for user interface (UI).
