Making a power glove from an old ski glove, using Adafruit fsr 4.4inch sensors. So from what I see in Sams circuit , the middle of din jack is +5 volt off the 7805 reg. and all fingers either go one side of fsr in glove to +5 volts together and the other side of each fsr in glove finger goes to its accompanying slew-atten. circuit in ,off pin 3 (-) side of op amp. and we go from there , right ?
