ModifyingtheEmbeddedProgram
You need to make two adjustments to the previous Arduino program to make
serial communication with Processing easier, and to implement the shift register
functionality. First, modify the print statements in the program you just wrote
to look like this:
Serial.print(c);
Serial.print("C,");
