//The section below lists all inputs and outputs for the program. 
//pc allows us to read data on the PC should we need to check that correct values are going through.
//LCD allows us to connect to the uLCD display and send commands as needed.
//sd allows us to send commands to the SD card reader on the board.
//DACout is connected to the speaker and outputs audio gathered from the SD Card reader.
//Sonr allows for the MBED to read in data from the EZ-LV Sonar.
//waver allows us to connect to DACout and play audio files as needed.
