Introduction The tags used to monitor wildlife can either be passive or active. Passive tags simply identify an individual, whereas active tags may send out a radio beacon or even collect data. These active tags, more commonly referred to as “bio-loggers”, are typically battery powered, and thus have limited life. This is especially true for […]

Introduction Our goal was to build a brain-computer interface using an AVR microcontroller. We decided that the least invasive way of measuring brain waves would be using electroencephalography (EEG) to record microvolt-range potential differences across locations on the user’s scalp. In order to accomplish this, we constructed a two-stage amplification and filtering circuit. Moreover, we

Introduction “A wireless mouse unit that requires no flat surface by using ultrasonic positioning.” For our ECE 4760 final project,we have designed a surface-less mouse interface using ultrasonic transmission as our final project in this class. The idea is to have a ultrasonic transmitter as a mouse, which represents the mouse’s position in space, with

Introduction Our project is building one set of NFC module including a NFC transmitter and a NFC receiver both using ATmega1284p microcontroller. We will be using coupled coils to transmit message modulated by a high frequency carrier, whose frequency is the standard frequency for Near Field Communication (NFC) – 13.56MHz (Wikipedia, 2013). In our project,

Introduction A modern-day twist on the classic theremin musical instrument. This project uses two IR sensors and the ATMEGA1284P microcontroller to create an inexepensive, easy-to-use theremin. The theremin is a musical instrument which is controlled by the electromagnetic field your body body produces naturally. One hand is used to control the volume of the instrument,

The Self Programming Mode (SPM) is a feature which enables a microcontroller to program its own flash memory. Using the SPM a microcontroller can program itself with an SPM code. The SPM is commonly used with the microcontroller Boot-Loader codes which help to program the microcontroller serially. In AVR microcontroller the SPM is available only for the code

ADC is an electronics device that converts the analog signals to digital number proportional to the magnitude of voltage. The ADC chips like ADC0804, ADC0809 etc., give 8-bit digital output. The controller device needs eight pins to receive the 8-bit data (For more details about ADC refer to Using Inbuilt ADC of AVR). Some applications need higher
