    Hi. Now I'm finally at the end of this project. All I have left is attaching the IR diode. I wanted to first test it out without soldering it on, but can't get it to work. Maybe I already burned the diode =OI have these specs: 1,5-1,6 V, 60 mA (120 mA max @ 10 % duty cycle).The diode you mention you run off of 5V and with a resistor, but it seems I need to drop the voltage 3.4 volts not to burn it out?I did a quick ohms law calculation(using 3.5 volts to get my 1.5 volts) with 60mA it gave me a resistance of 56 Ohms to use as a resistor. Does this seem appropriate?

    Try these values:static int UPKEY_ARV = 98; //that's read "analogue read value"static int DOWNKEY_ARV = 255;static int LEFTKEY_ARV = 410;static int RIGHTKEY_ARV = 0;static int SELKEY_ARV = 639;static int NOKEY_ARV = 1023;Seems to work for me. I haven't set it all up. just plugged in the display, but the buttons seem to do their thing.
