Project Introduction

The project of our group is the audio recognition system based on Arduino uno microprocessor. It could be divided into three parts: the microphone signal amplify circuit, the analog signal sample and transport system powered by Arduino uno microprocessor and the computer processing program. The expected work principle is using microphone amplify circuit to crate the audio analog signal and then sampling it by Arduino uno microprocessor. At the same time, the microprocessor will send the digital data to computer through serial port. In the end, the computer will process the received digital data and make the output of the whole system. This project covers electric circuit, microprocessor processing programming, serial communication and  c++ programming. Owing to the limitation of apparatus and the team size, the performance of the audio recognition system (the type of audio source which to be recognized) needs to be determined through the following work weeks.
