Hi All I want to build a circuit that log switches (3-4) position. like which switch was activate first which one was second and so on, and write it on eeprom. questions: is it possible? does any one saw such a circuit? can I add date and time stamp to eeprom log? can it be easy readable? i.e. lcd,pc screen..etc. 10x Tal -- http://www.piclist.com hint: The PICList is archived three different ways.
