Introduction: Arduino EMF Detector

About: I am a 35 yr. old licensed Iron worker/ Fabricator/ Welder/ Millwright but now in college currently in 2nd of 3rd year for Civil Engineering. I am a hacker & modder of all things and I love to fish, hunt, pl...

Here's a small, quick project you can do with an arduino, the EMF Detector!

Step 1: Circut

All you need for this project is

  1. 10- 330 ohm resistors
  2. 10- LED's
  3. 1-3.3m resistor
  4. 1-Solid core wire (this will serve as the probe)
  5. breadboard, wires, battery & connector for arduino to make it portable

Step 2: Hooking Up EMF

I can't tell you much more at this point. I left the circut diagram so you can figure the rest out. I will be making a permanent PCB for this EMF detector. I will upload picture's of the board layout in a few days when I get it done. Any questions leave them, I am usually quick to respond. Happy ghost hunting y'all!

Step 3: EMF Detector Code

This code is available at http://code.google.com/p/makezine/downloads/detail?name=EMF_detector_bargraph.zip&can=2&q=
  I did not write this code so I do no want to take credit for it I just built the prototype to my liking.

Step 4: Custom PCB for EMF

Here is the finished custom pcb for the arduino EMF detector.

Step 5: Hooking Up to Arduino

I changed the code and went from digital pins 2-6-8-10-12- gnd the on the analog side pins 5 and gnd.

Step 6: Top View

The finished EMF made portable. Hooked up to a 9v battery

Step 7:

    Could you post a written out explanation to the wire and led setup? I'm new to arduino and don't understand how to wire it based off the circuit diagram

    yes source codes all the same

    I'm guessing, based on the level of EMF indicated by the LED in this picture, I think your home/lab might be HAUNTED! :)
