We started studying eddy currents in physics this week, and I read online that the principle was used to determine the identity of coins. I found a really interesting YouTube video <a href=\"http:\/\/www.youtube.com\/watch?v=5QRKZBdkY4g\">here<\/a>, and I was fascinated with the idea. I have two Arduinos sitting around so I decided to use it as the microprocessor because, well, that&#8217;s what I have. I&#8217;m ordering two IR photogates to determine the time it takes for a coin to roll down a ramp with a strong magnetic field in the middle that will slow it down according to the material makeup. I&#8217;m also ordering a 16&#215;2 LCD output to display how long it took to travel between the two photogates and the coin identification.<\/p>\n<p>I&#8217;m excited about the programming challenges of this project. I have to figure out exactly when the photogates are tripped, come up with an accurate delta t, and then compare that to a range of known values to identify the coins. I can&#8217;t wait to get my supplies so I can get started on this new project. I hope I&#8217;ll have fun pictures and updates on this project soon!!<\/p>\n","protected":false},"excerpt":{"rendered":"<p>I started planning for a new project this week.
