Searching for info regarding the PS2X Library

I added the comma and it makes it much easier to read smiley-razz Is there a way I can tell it to kick the next set of values down to the next line on the serial monitor?

Yea, that was my fault, change the last one to Serial.println(Input2);

1501,1501,etc.
Is there something wrong with how I used/ setup the map function?

The joysticks work exactly like a potentiometer, so full up is 255 and full down is 0, so in between is 128, and when you map 128, that equals to ~1500. Those values should increase and decrease when you move the stick, if it doesn't then there may be a problem with the wiring or the controller itself.

How much voltage is the controller getting, 3.3 or 5V? I have a regular and a wireless controller and they only seem to work at 3.3V.
