For our ECE 4760 final project, we designed and built a bicycle dashboard which displays the cyclist’s pedaling power, speed, cadence, and distance to enhance training. The major motivation of this project was to replicate a commercial product at a dramatically reduced price point. A commercial power meter costs around $1000 for just the instrumented […]
ukule-LED is a ukulele with LEDs embedded in its fretboard. These LEDs can light up in configurations corresponding to different chords, which can aid the ukulele player in learning how to play certain chords, or can act as a chord reference for a more advanced player. ukule-LED has two modes of operations. First, in “play”
Introduction This project visually displays the frequency content of an audio signal using an 8X3 grid of LEDs. A microphone and amplifier collect analog audio input which is sampled digitized using the MCU’s analog-digital converter. The samples are buffered and and a 32 point discrete cosine transform is performed in real time to obtain 32
Introduction For our ECE 4760 final project, we implemented an interactive CPR training dummy which can coach the trainees through the CPR process with a LCD to display instructions. The prototype CPR training dummy built is a budget-friendly one that contains a re-programmable Atmel ATmega1284 microcontroller and other hardware components so that it can interact

Introduction For our final project, we have decided to use the microcontroller provided to make a device which would measure body fat percentage of one’s body. The basic principle behind this project is known as bioelectrical impedance analysis. This technique uses a small alternating current flowing between two electrodes attached to skin surface to determine
we designed and implemented a speaker recognition device that acts as a lock triggered by the sound of your voice saying a specific passcode. The implementation uses hardware filtering from a microphone and many signal processing concepts in software. All software and matching is implemented in the ATmega1284p. The lock has two modes: training and
Introduction Musical Instrument Digital Interface, or MIDI, is a standard that describes a protocol, digital interface and specific physical connections that allow electronic music devices and computers to communicate with each other. For our final project, we created a MIDI glove that is capable of connecting to a virtual synthesizer on our computer and controlling
Introduction “A resistive touch screen robot that follows a user-defined path input by drawing on the touch screen.”” We designed and implemented a robot that follows the path drawn on a touchscreen. The touchscreen is mounted on top of the robot, and once the path is drawn, and the user picks up their finger, the
SingLock is a pitch-based security system based on ATMEL MEGA1284P microcontroller featuring two password protection stages: one based on a 4-digit numeric personal identification number inputted via the keypad and another based on two pitches inputted via the microphone. Most security systems we find today are keypad and/or keyboard-based. Speech, rather than button-pressing and/or typing,
Introduction The Skittles Mini-Factory is self-contained repackaging unit that separates Skittles by color. Once separated, the Skittles are resealed in individual plastic bags. The Skittles are dispensed one at a time (either automatically or manually) onto a light sensing module. Red, green, blue, and white light are reflected off the skittle and read by
