I have another idea I want from the table I'm building that is a little hard for me to figure out so I thought why not post it here
I'll have circles cut out of the table with Plexiglas over set in the hole so it will be flush with the top of the table. The Plexiglas will not be as thick at the actual table so there will be a small amount of space to work with. I want to put in a sensor that can detect if a cup is set onto that spot above it. Now for the electrical part. I want the circle to be lite up green when there's nothing there and when the sensor senses the cup I want it to switch off the green lights and then switch on circuit 2 (which will be a different color LED circuit) The problem I have is that I need a sensor that can go through Plexiglas (prob 1/16" thick) and sense the cup and not be affected by the LED's that are lite. I figure a single pull double throw switch would work best. I looked around on digikey.com and found this one. Its magnetic and I really don't want that but unless someone has a better (same price or cheaper) solution this I guess is my best bet. It's only 40 for 10 of them which I can handle. This is more of a DIY project to get me more familiar with electronics and give me some more hands on experience with different components and I figured making something like this table with everything I can think of in it would be the best idea. Also the cheaper the stuff the better because I'm paying for my college classes as well so every penny counts as my parents would say
As always I'm open to different solutions to my project so if you have any idea's they would greatly be appreciated.
Thanks in advance,
Joe
