Abstract/Artist Statement

Our team has designed and built a portable and user friendly piano note recognizer. This device has two modes of operation. The first mode displays notes on the musical staff as the user plays the piano or other musical instrument. The second mode prompts the user to play a note and verifies that the correct note was played on the LCD screen. This project is designed, built and thoroughly tested. Several algorithms were considered for analyzing the audio signals. After testing a few, we developed code in MATLAB to process the audio signal and translated our solution to the Arduino Nano platform. Our unique design is implemented on our own printed circuit board that we created using Eagle ayout tools. The finished portable battery operated device will recognize single notes one octave above and below middle C.
