Self Reliant Power and Data Management System

Self-Reliant Power and Data Management System Using Atmega644

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

Brain-Computer Interface Using Atmega644

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

NFC Transmitter and Receiver

NFC Transmitter and Receiver Using Atmega1284

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,
