For each lighthouse you'd need an LED, a resistor, and a 10F200. Write a generic 10F program that had a dedicated area for the on/off times table, then customize each one on the fly. ***************************************************************** Embed Inc, embedded system specialists in Littleton Massachusetts (978) 742-9014, http://www.embedinc.com -- http://www.piclist.com hint: The list server can filter out subtopics (like ads or off topics) for you.
