In lines 3 to 5, we define a global TvRemote object named tv , a string named
command that holds the current command, and a Boolean flag named
input_available that is true when the sketch has received a new command. As
usual, we initialize the serial port in the setup function.
The Arduino calls the serialEvent function defined in line 11 when new data
arrives at the serial port. (Learn more about serialEvent in Serial Communication
Using Various Languages, on page 255.) We append that data to the command
