D Duckvader New Member Oct 21, 2006 #1 BIOFEEDBACK MONITOR using IC LM 555. I need a link or site that can provide with the required software for this circuit. Does anyones knows how to get this software to run it or the written program to display the results. I've add a picture of it under attachments. It is a biofeedback monitor circuit using IC LM555 mainly used to measure Galvanic Skin Response. Thanks. Attachments 1.JPG 20.6 KB · Views: 188 Last edited: Oct 22, 2006
