I use this part for all of my current measurement. It works off the 5v supply and gives a nice 0 - 5v feedback that is easily read by the PIC.

Light travels faster than sound. That's why some people seem bright until you hear them speak.

Change resistor position
Put your sense resistor between load and ground. Then you see same current but DC voltage is only 0.2v. This is the most common way to measure current with sense resistor.
