I guess you once crossed a highway without being hit, so you will=20 continue to do that? IIRC you quoted the right resistor values but the wrong currents, so=20 your circuits will work, but others that base their deign on the current=20 you mention will fail :( -- Wouter van Ooijen -- ------------------------------------------- Van Ooijen Technische Informatica: www.voti.nl consultancy, development, PICmicro products docent Hogeschool van Utrecht: www.voti.nl/hvu --=20 http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist .
