Use an Arduino microcontroller to sense invisible electromagnetic fields using wire, a resistor, and an LED. Aaron ALAI's EMF detector project is awesomely simple to make and fun to use. An upgraded version can be built using an LED bargraph for more 'meter-like' functionality. original project can be found here - *******www.aaronalai****/emf-detector additional info, and Arduino sketch - *******blog.makezine****/archive/2009/05/making_the_arduino_emf_detector.html audio/video by Collin Cunningham
