No idea; did you try what I suggested in reply #13?Please post some links to that wireless PS2 stuff.
And PS2 usually does not stand for playstation 2, it was the connector used for keyboard and mouse before USB took over.
So I can get it to send 1's to the serial monitor but not to a notepad/IDE. Interesting note, when I remove the USB cable from the PC and power it using my battery it sends L's instead of 1's.
http://www.instructables.com/id/Wireless-Keyboard-With-Arduino/ is the wireless PS2 project.
After reading more I found the PS2 library can't do the .press command which is what I need because I want to hold down 3 keys at once.
