n our final project, we designed an electronic multifunction instrument with a LCD touch screen and a microphone. The user can play three kinds of instruments on it — xylophone, flute and piano. Each instrument has a different interface and timbre. The piano part has a record/replay function which can echo the song previously played […]

Introduction We created a wearable game controller that uses accelerometers to acquire action of the hand and then maps an action to an arbitrary keystroke. The types of actions we are trying to recognize should be suitable as input control for video games. We placed 3 z-axis accelerometers on tips of the thumb, the index

We have created a real-time video object tracking / shape recognition device, and a fun game library to demonstrate its abilities. For our project, we wanted to push the video sampling and processing capabilities of the ATmega644 8-bit microcontroller. Using a high-speed analog-to-digital converter as an input device, we were able to sample a reasonably high-resolution grayscale image from a

For our ECE 4760 final project, we designed and built a wireless computer pointing device with accelerometer based movement control. Our implementation allows the user to wear a set of hardware (a glove and connected armband) and control a cursor through different hand orientations and finger presses. Users can operate their computers with their hands

Introduction “A device that tracks sound impluses with a three microphone array” We designed and build a 2-dimentional Acoustic Impulse Marker system which is capable of detecting a sharp sound anywhere in its vicinity and precisely marking its source vector with a servo based pointer. Our system has a full 360 degree range, and is

Our acoustic wayfinding device utilizes ultrasonic range finders and haptic feedback to facilitate indoor navigation for the visually impaired. The technique of acoustic wayfinding uses auditory cues, such as sounds from the natural environment or sounds created artificially, to determine an individual’s surrounding physical space for the purpose of navigation. Our device is an automated

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

In this article, we will explain how to communicate to an external EEPROM from the AVR Atmega32 MCU using the I2C communication protocol. So let’s begin our tutorial on how to interface an EEPROM (AT24C16A) with AVR Atmega32. You will usually need an external EEPROM when your system has a certain set of user configurable settings that you need
