 // Samsung IR Remote for Arduino
 // Based on https://github.com/ironman977/SamsungIRRemote
 // forked from Martin Meise to use with Samsung UE40KU6079
 // probably works with all Samsung K Series (use Button A and D)
 // -- instructions for UE40KU6079 --
 // Power on your TV and Press Button D
 // You should now see an overlay display
 // Navigate with Arrows up and down on your TV remote to Options
 // Press the right arrow to select (use back or left arrow to go back)
 // Select SW Model and change it form UKU6000 to UKU6090
