I have a science fair coming up and had a really good thought, however I'm not sure how I would go about doing it... So the thought is a refrigerator with product recognition abilities. Basically there will be something with basic information under a product (bottles, cans, etc.) which maybe has the expiration date and the bar-code number (maybe just the bar-code number). So in the fridge, there will be a sensor of some kind to recognize the products. Then that will be transferred to a computer so it can display a list of the things inside the refrigerator. I have a good knowledge of Vb.net and basic knowledge of electronics (resistors, capacitors, transistors, SCRs etc.). I really have no idea for how this would work out, I know it's doable but not sure how.
