I have a question regarding sensors triggering high states in a specific order. I have 8 ldr's placed in 8 chairs. When no light is detected by a sensor (when a person sits in the chair) it triggers a relay. My question is if it is possible to have a specific sequence on the relays, no matter which chair is occupied. So relay #1 is triggered if one chair is occupied, relay #2 is triggered if 2 chairs are and so on. No matter witch chairs are sat upon.
Hope this makes sense. Thanks in advance. R
