Send Pronto Hex via an IR LED connected to Arduino Pin D9. Make sure you do not send a blank (" ") as the last character. Applied fix for Leonardo from https://github.com/probonopd/arduino-infrared-pronto/pull/1 to sendandreceive.ino -- TODO: Fix sendRaw to specify length as "sizeof(signal)/sizeof(int)" as in http://forum.arduino.cc/index.php?PH…
