I saw someone make an EMF detector on youtube, so I decided to try making one myself. I don't have a bar LED, so I'll use regular LEDs.


- detects EMF
- the higher the EMF, the more LED's light up
parts:
- 9x red LED's
- 9x 330 ohm resistor
- 3.3M ohm resistor (I used a bunch of smaller resistors and connected them in series to get 3.3M ohm)
- 1x probe to detect emf (a wire)
