Nice LED array

This LED array came out of an old Sky+ box (you know the one, it's used in all the Sky advertising). The LEDs are multiplexed, but if you only want to have one on at a time it is easy to drive them directly from an 8-bit port on a PIC. I rigged it up to a PIC 16F690 set up for analogue reading so the LEDs work like a neat little meter with the green arrow at the mid-point. I'm thinking of using this as fuel/air meter.
