Measuring motor speed and display result on LCD using ATmega8 microcontroller

Leave a Comment / Using Atmega / Tech Master

For measuring motos speed there can Optical interrupter used like H21A1. This is a device where IR LED and photo-transistor is coupled in to plastic housing. The gap between then allows interrupting signal with opaque material and this way switching the output from ON to OFF. This device can be connected to Microcontrollers ICP pin and […]

Secret Knock Detecting Door Lock Using Atmega

Leave a Comment / Using Atmega / Tech Master

Protect your secret hideout from intruders with a lock that will only open when it hears the secret knock. This started out as a bit of a joke project, but turned out to be surprisingly accurate at judging knocks. If the precision is turned all the way up it can even detect people apart, even if

Eye in the Sky Security System Using Atmel Mega32

Leave a Comment / Using Atmega / Tech Master

Introduction We have used the Atmel Mega32 AVR microcontroller to construct an affordable, high end security system designed to protect valuables in a single room of a house or property. According to national surveys conducted by the department of Justice, property crimes are ten times more prevalent in the United States than violent crimes. On the Cornell

RoboDog using ATMega32

Leave a Comment / Using Atmega / Tech Master

Introduction The project, Robodog?is an autonomous car that follows sound. The car can follow almost any audible sound that human can create by using three onboard microphones. This project was possible because of the fact that the speed of the sound is relatively slow compare to the MCU. We took apart an old remote control

Neural Net Helicopter Using Atmega32

Leave a Comment / Using Atmega / Tech Master

Introduction and High Level Design Our project was to design a two degree-of-freedom stationary helicopter, autonomously controlled by an evolving neural network. A normal helicopter has six degrees of freedom, which makes any form of control exceptionally hard, let alone autonomous control. What our design does is limit the movement of our system to just

A Budget Pachinko Machine Using Atmega644

Leave a Comment / Using Atmega / Tech Master

Pachinko is a game in which a ball drops down through a large quantity of pegs and the objective is to catch that ball in a fixed basket. The concept behind our machine is novel in that it was built using mostly discarded and salvaged parts. We built a pachinko machine because we wanted to play

POV Magic 8 Ball Using Atmega1284

Leave a Comment / Using Atmega / Tech Master

1.Introduction In our final project of ECE 4760, we designed a magic 8 ball, which is a rotating POV (persistence of vision) display controlled by voice commands. In our design, users can ask yes/no based questions via a small speaker, and the rotating POV part can display random answer of yes or no to answer
