[Michael Gerstenmayer] has been very successful in developing a biofeedback system . He’s based the build around an Arduino and started adding different chunks to the project to develop a full-featured unit. It can take your temperature (with an IR sensor…. not the hard way), measure your galvanic skin response (conduc...
