forgive my ignorance but you guys are the experts so who better to ask.
I have a project that i’m working on where I have to measure slight changes in skin resistance and display that information on a graph.
originally I had a circuit that had a wheatstone bridge that’s connected to a instrumentation amplifier and I had that connected to an oscilloscope to check check the signal coming out.
that didn’t work out too well so my teacher gave me an MSP430F1611 and a DZ1612 board without much explanation as to what to do with them.
he drew a picture to connect the following
msp430->voltage follower->Op amp → Resistor bridge->instrumentation amplifer-> software to display graph
from what i can tell is that it has to do with signals …there a sine wave on one end and you end up with a square wave kinda on the other end…and some how that would be the output of the small changes in yor skin resistance.
does this make any sense to any body
?
