An LED EMF detector!

I now enjoyed working with the Arduino, therefore, I wanted to make another type of EMF detector and try out different types of detectors that do the same job. The one I previously made indicated the level of EMF through levels of bars in the bar graph. However, this time I wanted to make an EMF detector that indicated the level of EMF through an single LED light. So;

Bright = High level of EMF radiation level (Run away A.S.A.P and save your life)
Dull = low level of EMF radiation level

IT WORKS!!!!!!

However, the LED light is fuzzy. It doesn't really show a clear understanding of how much radiation there is. Therefore, I prefer to stick with the Bar-graph EMF detector as it shows the level of radiation through clear measurements.

The more I experimented and worked on the Arduino and the programming, the more I began to understand the whole concept and it made more sense.
