IFF System for Infantry

IFF System for Infantry Using Atmega1284

Introduction “An encrypted laser-based friend-foe identification system to prevent friendly fire in battle” This project implements an Identification Friend-or-Foe (IFF) system for use by soldiers to prevent friendly-fire. The inspiration for the project is derived from Identification Friend-or-Foe (IFF) transponder systems currently used on fighter aircraft and military vehicles. Fighter aircraft fitted with an IFF […]

Bat Hat

The Bat Hat Using Atmega1284

Introduction “An ultrasonic range-finding hat with variable haptic feedback for obstacle detection.” -Project Sound Bite For our ECE 4760 final project, we designed and implemented an ultrasonic range-finding hat that uses haptic feedback to alert its wearer about obstacles in his or her path. The hat is equipped with an ultrasonic transmitter/receiver circuit, which is capable of

Flex Sensor Interfacing

Flex Sensor Interfacing with AVR Microcontroller Using Atmega

In this tutorial we are going to interface FLEX sensor with ATMEGA8 microcontroller. In ATMEGA8, we are going use 10bit ADC (Analog to Digital Conversion) feature to do this job. Now the ADC in ATMEGA cannot take a input more than +5V. What is a Flex Sensor? A FLEX sensor is a transducer which changes its resistance when its shape

AVR based Sensor Keyboard

AVR-based Sensor Keyboard Using Atmega

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 Audio Homing Robot

PeanutBot, The Audio Homing Robot Using Atmega32

Introduction Sensing in autonomous vehicles is a growing field due to a wide array of military and reconnaissance applications. The Adaptive Communications and Signals Processing Group (ACSP) research group at Cornell specializes in studying various aspects of autonomous vehicle control. Previously, ACSP has examined video sensing for autonomous control. Our goal is to build on
