3 wire fsr to ssc analog 2 wire abcd

Ok I think that I have most of the answer by reading old posts.

The fsr ground connects to the - on ABCD
The fsr yellow analog output connects to + ABCD

But I am unclear as to where I jumper the fsr red power wire to the +5v regulated output on the ssc board.

Thanks Wayne

The row of pins closest to the Atmel chip are the analog inputs. On the outside row, the (-) is ground and the (+) is 5vdc from the regulator. The inputs are CMOS so I don’t recommend testing with them open (unconnected). So you need to connect as follows:

FSR ground = (-)
FSR positive = (+)
FSR analog output = (A,B,C,D)

Thanks Jim, tried this and it works very well.

I am in the process of playing with each resistor to learn how the sensitivity varies with pressure from my finger

So in the ssc32 configuration I can attach 2 fsr ± ± and use A and B

Will it be safe to attach 2 fsr to each ± and then use all 4 analog returns A B C D ?

Thanks Wayne
