i found this button in a drawer and it fits perfectly in the hole I want to install it in...I think I got it at RadioShack years ago. I googled it and all I found was this diagram:http://www.sci.com.tw/PRODUCTS/AUTO%20ACCESSORIES/(R13)%20Car%20Switch/(A3)%20PUSH/R13-553.html
I can't really make sense of it. Right now I have pin 3 (LED pin) through a 1k resistor and in ground, pin 2 to the arduino and pin 1 in 12V. The arduino also shares the 12V ground.
The arduino isn't recognizing the button. i want the LED in the button to stay on all the time which it is now, but no pin reading. Any idea how I could rig this up to work with an arduino? i'm so bad at switches...
Thanks for any help!
