How do I make a lamp last?? > Normally use about 100k with 230V, so you probably want to use about 3 100k resistors in series - you will probably need more than one resistor to be within the voltage rating of the resistors. -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
