New to Arduino, first time posting.
I'm having a blast tinkering with electronics, but I'm running into a problem. I'm doing the DigitalReadSerial tutorial-http://arduino.cc/en/Tutorial/DigitalReadSerial
And the LED at 13 stays lit, but gets brighter when I press the switch I have. I've even tried moving the Arduino thinking that the fabric of the surface I'm working on was giving it interference, but same thing. Is this what I should be expecting? Or might something be wrong with my Arduino?
I've moved the circuit around on my breadboard too, just to rule that out.
