This project consists of 2 8x8 led matrix which have been connected together to form a 16x8 led matrix. No multiplexing or any other technique(such as using shift registers) is used to reduce the pins required for interfacing with microcontroller. This is because an atmega2560 was used in this project. Also an HC05 bluetooth module was used for communication. A bluetooth android application was used for communication which first converts the speech to text then outputs the string via bluetooth.
