Random LED 4x7seg display I found and extracted from a bathroom scale.

I like the way this component works, but the pinout has no consistency or patterns.

	COMPONENT PINOUT

----------------
| P  | +/-/DIO | Function
|--------------|
| 1  | + -> IC | Power in for 1st digit
| 2  | - <- IC | Power drain for A segments
| 3  | - <- IC | Power drain for F segments
| 4  | + -> IC | Power in for 2nd digit
| 5  | + -> IC | Power in for 3rd digit
| 6  | - <- IC | Power drain for B segments
| 7  | - <- IC | Power drain for E segments
| 8  | - <- IC | Power drain for D segments
| 9  | - <- IC | Power drain for H segments
| 10 | - <- IC | Power drain for C segments
| 11 | - <- IC | Power drain for G segments
| 12 | + -> IC | Power in for 4th digit

	Though not shown in the diagram, H is the decimal point. (I'm assuming that this is not on all 7seg displays)
