To continue decreasing the size of this device, I'm changing out the Arduino Uno for the Arduino Nano. I've almost brought 2 more Flexiforce FSR Sensors that I have connected up, bringing the total up to 5 (one for each finger).

I had a big issue when I went about doing this, some sort of floating voltage came about - in both boards... giving me random readings from the sensors. Had to un-wire everything and wipe the boards clean, re-type out the code and re-upload, and what I think solved it was connecting the 5V with a jumper wire directly to the ground for a moment... maybe it drained this floating voltage out of the circuit?? 

No idea how this came about??...

I've also taken out of the breadboard and the Arduino code, the LED related software and hardware, as this will not be needed in the final product form and allows me to know the minimum size needed for my breadboard.
