    Adjustable Constant Current Source

    Hi. I'm designing and implementing a NiCAD battery charger for fun. So far, I have my LM317 outputting approximately 1.2 A in a constant current source configuration. My question is how do I modify it to be an adjustable constant current source (say through my microcontroller) so that once...
