Hi jerrya.net,
I need to create a 'garbage can' which detects if someone throws something into it. Because of the specs of the project we want/need to create a strip of IR-emitters and IR-receivers (like 10 pairs per garbage can).
I was wondering if you think I could use the parts you've used in your setup? As we need to create 4 garbage cans, we have 40 pairs which need to be checked. Therefore we probably need shift registers.
