Hi Richard (and anyone else that looked at my mess) What I had put up was a non working schematic, I've tried so many many variations that I just put up the section that I though needed to be sorted out. I was hoping it might allow someone the idea of what I was trying to do. Ie using the available current from an output pin on a pic to drive a 2n2222 that in turn switches a larger "power" transistor which hopefully switches off and on with my desired pattern.. I think I'll correct it to the point where it might make sense and get rid of the schematic portion I have on there. That might eliminate a lot of the confusion. If you can look at it again (give me an hour to correct and upload) it should make more sense. Thanks! Dave -- http://www.piclist.com#nomail Going offline?
