This is the project developed for second year project for the courses EE251-Principles of Electrical Measurements and EE254-Electronic Instrumentation. A device was developed to map colors to sound for visually impaired people.
Group Members: Sanjaya Herath, Madri Madawala, and Ishara Madushan.
Supervised by: Dr. Janaka Wijayakulasooriya
Measurements obtained from an LDR was analyzed for different colours. The firmware was developed using Arduino and signals were analyzed using MATLAB. Red, Green and Blue LEDs were illuminated on a surface sequentially and the LDR measurement was acquired. The three dimensional dataset was project to a 1D vector using FDA. Then each differentiated class was mapped to a specific music note.
