Step 6Pull-up resistors
Test first:
Hook up a multimeter in beep mode to the VCC tab and in turn connect it to each of the other tabs. Without even pressuring it, make sure it does not beep. If nothing is touching, then you can pressure each sensor individually to see its resistance range.
Update: The resistiance range of this sensor is ideal for the internal 20K ohm pull-up resistors of the Arduino. So you can skip the rest of this step and look for the right code to activate your internal pull-ups in the next step.
Cut a small piece of perfboard with conductive copper lines, at least 6 x 6 holes big. Solder as seen in schematic illustration and plug in to your Arduino board. For more information on pull-up resistors and why they are necessary, follow this link >>

Clip the crocodile clips to the correct conductive tabs of your pressure sensor matrix.
