I'm new to electronics and have a question: I have some contact sensors that I want to use in a project (came from a Nintendo Zapper gun). Can they be used in conjuction with analog and digital ICs? What do they register in their open state as, L or H ? -- Michael McCann UFORC .................... http://www.ufo.pair.com Mailing List ............. uforesearch-list@ufo.pair.com
