Code:

There are two part of code: get value of Remote and Send command.

Get Value of Remote：

Open revTest of IRSendRev Library, open Serial Monitor. Take your Remote, press a button, then you can find a series of number had been printed.

This series of number is what we need, note it, we'll use if later.
