Hello all,

I just picked up my first arduino and I was hoping that I might be able to get some help/advice on a project that I want to try to have completed by Halloween.  My best friend and I are going to do a little Superman/Lex Luthor cosplay and what I want is to have a hunk of "kryptonite" that glows when it gets close to Superman.  The way I thought I could achieve this is to use the arduino to control a lighting kit (maybe el wire).  To get the lights to pulse or turn on only when Superman is close, I thought I could connect an rf receiver to the arduino and sew/connect an rf emitter to the superman costume.  I thought that maybe I could program something into the arduino that would regulate the voltage going to the lighting kit in proportion to the signal strength received from the rf emitter.  Can anyone help?  I have absolutely no experience with stuff like this.  Thanks.

It is possible but you would need to find a RFID module with a RSSI (receiving signal strength indicator). You may need to do some research first, on them and shop around.

Post any links you find.

RF signal strength probably will not work as expected.
Consider the daffodil. And while you're doing that, I'll be over here, looking through your stuff.   8)

Will do.

Could be, but why do you say that?

IR led(s) in the Superman costume and IR detector in the K?

Or... it's a cosplay. Cheat.

Because many things affect RF signal strength. Distance is only one of them, and is not even in the top 5.

Perhaps a magnet and a hall effect sensor. - Scotty
