I'm busy doing my finals project, and I need to have 5 photo-transistors come together on the same pin to trigger an event whenever one of these transistors drops it's voltage because an object is moving past it. I've been struggling for multiple days to fix this now, but I can't seem to get it working quite right. Do any of you see/know what I'm doing wrong? circuitry efficiency is not an issue here. I've added a circuit diagram.
