Question

Write a program that will read a single human readable character from the serial port and send back a string that represents the Morse code pattern for that character TA Signature:. - Date: /201 Write a function that processes the Morse code pattern by playing the correct tones for each character and also printing the Morse code pattern to the serial port. Dat.../201 -Your program should use these values for the lengths of the various delays you'll encounter in this assignment Type Dit (short) Dah (long) Space between dits and dahs500 milliseconds Space between letters Space between words Duration 100 milliseconds 300 milliseconds 300 milliseconds 700 milliseconds
