William Finucane of revoltlab posted this easy lie detector project on the Mad Science website. The hardware consists of nothing more than an Arduino, a 10K resistor, wire and some tin foil. (You didn’t use ALL your foil for your hat, did you?) The device operates on the galvanic skin response (GSR) principle and detects […]

Arduino & iPhone = GSR lie detector
Anna Dumitriu, Tom Keene and Alex May recently gave a presentation at 17th International Symposium on Electronic Art in Istanbul demonstrating how to build an Arduino to iPhone/Android interface with GSR sensor. A GSR sensor connects to an Arduino board. The Arduino generates an audio tone mapped to value of electrical resistance in the skin. […]
