This digital stethoscope can be used as computer aided diagnosis (CAD) applications for the detection of cardiac murmurs. It can assist physicians in analyzing cardiac signals in real time during auscultation to reduce the risks of not detecting heart murmurs conditions. The Stethoscope system is built based on ATmega644 AVR microcontroller and custom-built sensor to […]

The goal of this project is to build image scanner that uses a phototransistor array to detect light intensity instead of CCD overlaid with a photoactive layer of silicon. The system uses internal ATmega644 Analog to Digital converter to capture light signal from sensor. The data then transmits to MATLAB for image processing through serial […]
