The result of this project is a 3D printed, arduino nano driven EMF detector. Yes, you could go for hunting ghosts, or you could try to find sources of electro magnetic fields creating noise in your speakers, or killing the functionality of your gadgets.

Yes, this project is based on some videos I found. However, I thought I could push it further. This design does only use one resistor to drive all of the LEDs, other designs were using 10 of those, which is kind of a waste. And, I thought it would be cool to be able to change the sensitivity. So I added a switch to do exactly that.
