what circuit layout does capsense use?

Using Arduino Sensors

Using capsense library with multiple inputs, do you use this layout?

Or this one?

Or something else?

edit: On the second drawing I meant to have the third input after the resistor.

If you look at the demo sketch on http://www.arduino.cc/playground/Main/CapSense you will see that it describes the circuit for a single send pin and multiple receive pins:

CapSense   cs_4_2 = CapSense(4,2);        // 10 megohm resistor between pins 4 & 2, pin 2 is sensor pin, add wire, foil
CapSense   cs_4_5 = CapSense(4,5);        // 10 megohm resistor between pins 4 & 6, pin 6 is sensor pin, add wire, foil
CapSense   cs_4_8 = CapSense(4,8);        // 10 megohm resistor between pins 4 & 8, pin 8 is sensor pin, add wire, foil

One resistor per sense pin.

(Other stuff in that may help, too.)
