Hello everyone this is my first time here! I am interested in electronics, talked about getting an arduino for years, and recently bought one for myself!
I need all your help in guiding my first project in the right direction!
The main goal of my first project is to keep silverware out of the trash at work. I work at a restaurant, and a lot of silverware gets thrown away on a daily basis by accident.
My idea is to tune some type of metal detection to pick up when a silverware passes by into the trash can. If I can get the arduino to recognize the silverware passing as a certain numeric value, I can use that value to tell the arduino that it's time to sound a buzzer and flash some lights. And yeah basically the idea is a metal detector fit over a trash can lid.
So here's the problem. I did a bunch of research on how metal detectors work, and came up with a bunch of information. I found this project which makes me believe this is feasible: http://www.youtube.com/watch?v=Rf-FbK8ieHY
I've been reading this article too http://www.deeptech-bg.com/Tumanski.pdf which has a lot of great information, I just don't know how to interpret this into something I can use for my project. I don't want to make something more complicated than I have to, so any insight you may have would be greatly appreciated!!!
I don't have time at the moment, but I have done some more research, and can explain a little more about what I think I know about VLF, and EMF detection, which may help you help me more. So i'll post more tomorrow, and hopefully get some feedback in the meantime.
Thanks!
