Did you set the line ending to newline? (it is part of #6 instructions)
Oh right, now i know what the newline thing means 
It isn't that simple. It depends on the current draw for the backlight.
I thought of that too. According to multimeter it takes so little current that 10A range does not recognize it when running at "20".
But when i take it upto "220" pwm it will show something about 10mA. I really do need to get me a new fuse on the 400mA to get more accurate results.
