Hi I'm looking to hook up the miltone etape sensor:
http://cdn.sparkfun.com/datasheets/Sensors/ForceFlex/eTape Datasheet 12110215TC-8_040213.pdf
They mention using a voltage divider. The example I found used pins 2 & 3 where pin 2 goes to gnd. pin 3 goes to one side of a 560 resistor and to analog input 0. the other side of the resistor goes to 3.3v and to aref.
I was wondering what the equivalent of aref might be and if I wanted to use multiples of this sensor if someone could suggest a wiring configuration? sorry I'm rather new to all of this..
