/* DVD IR Synchronizer for Toshiba SD1091EKE
|
|
* Developed for Art Installation by Steina
|
|
* Code written by Joe Foley <foley@ru.is>
|
|
* on 2013-09-08
|
|
*
|
|
* Requires libraries:
|
|
* Arduino-IRremote https://github.com/shirriff/Arduino-IRremote
|
|
*
|
|
* More codes at http://www.lirc.org/
|
|
* The compatible remote is SE-R0301
|
|
* We use the codes for the SE-R0031
|
|
* http://lirc.sourceforge.net/remotes/toshiba/SE-R0031
|
|
* Note that this has some similar codes
|
|
*
|
|
* The IRremote library uses Pin 3 for the Anode (longer pin)
|
|
* We have made a ground pin on Pin 4 for the Cathode (shorter pin)
|
|
*
