He suspected EMF interference so as a quick first step he decided to throw together an EMF detector using an Arduino. It uses a bank of LEDs as an indicator bar to reflect the EMF picked up by the ...

The sensor can be pointed at an object, and the Arduino can sense the brightness of that one point. Since this camera compiles an image so slowly, it sometimes has a problem with varying brightness.
