O2 sensor meter

[Howard Chu]

Y'know, what would really make something like this useful is a dual
meter, where the second meter is a delayed/moving average. Then you
could actually see how well the ECU is doing at homing in on stoich.
How about a buffer from the O2 sensor that charges a small cap, with
a short time constant to feed the second LED bank?
