/*
 * IRremote: IRsendRawDemo - demonstrates sending IR codes with sendRaw
 * An IR LED must be connected to Arduino PWM pin 3.
 * Version 0.1 July, 2009
 * Copyright 2009 Ken Shirriff
 * http://arcfn.com
 *
 * IRsendRawDemo - added by AnalysIR (via www.AnalysIR.com), 24 August 2015
 *
 * This example shows how to send a RAW signal using the IRremote library.
 * The example signal is actually a 32 bit NEC signal.
 * Remote Control button: LGTV Power On/Off.
 * Hex Value: 0x20DF10EF, 32 bits
 *
 * It is more efficient to use the sendNEC function to send NEC signals.
 * Use of sendRaw here, serves only as an example of using the function.
