The code starts with an enumeration that contains all the constants we need:
the length of each control code ( CMD_LEN ) and the control codes themselves.
There’s one entry in the enumeration for each key on our remote control.
In line 33, we define an IRsend object named tv that we’ll use to send commands
using the send_command method. send_command uses IRsend ’s sendSAMSUNG method
because in this example we’re using a Samsung remote control. If you’re using
a device from Sony or Sharp, you have to adjust the code accordingly. Note
