Digital dash

[Matt Cramer]

	I've been thinking about building a digital dash for my Dart.  While I
could put together a circuit on my own that does LED bargraph readouts
without too much trouble, a three digit digital readout would be more
accurate.  Yesterday I decided to see if I could find any sites on the
Internet that might list what kind of IC's might be helpful in such a
circuit.  I got as far as figuring out that I could use some kind of off
the shelf 8-bit ADC, but is there some kind of chip that will take the
output from an ADC and use it to control a (preferably three digit) LED
display?  If so, what's it called, and who makes it?
	This would be enough for me to put together a digital temperature gauge,
fuel gauge, or similar gauge, but I'm also wondering about tachometers and
speedometers, as a digital tach would be a nice addition.  Is there some
kind of IC that will accept the kind of signal I can get from the
distributor as an input, and return a value that corresponds to its
frequency, or something else I could use for this?
	Thanks in advance.  There seems to be so many kinds of IC's out there, I'm
not sure where to start!
