Hi! I'm just a novice guy who wants to create a simple reverse vending machine using LEGO Minsdstorms NXT that can accept plastic bottles and can dispense tickets. I managed to make the ticket dispenser but I can't seem to find a way to detect the PET bottle in the first place. Is there any way of detecting PET bottles using LEGO Mindstorms NXT?
Any help is appreciated. Thanks!
