can anyone recommend any LCD and driver I should use. Any codes
available?

Are you trying to make a tachometer for your car? what type of
tachometer are we talking about? What exactly is it that you want to
measure. Measuring the speed of your transmision is kind of hard but
measuring the speed of a bicycle wheel or a robot motor is not that
hard? Before I can give an answer I have to knwo exactly what you
want.

Refereing to the LCD. If you are lucky you can get a leftover one
from an old rado or electronic equipment. If not then it will all
have to depend of what options you want on it. For example in
jameco.com they sell a 1 line 16 character LCD for $13. if you want a
2 line then thats going to cost you extra. If you want graphics like
bars and what not then I would recomend you buy one specifically for
that purpose and its going to cost you extra. There are even ones
that have 4 lines 40 characters per line. I know I'm being kind of
vague here but we( I ) need to know what exactly is it you want. If
is just for experimentation purposes then buy the cheapest one. a 1
line LCD or the more comon 2 line LCD.
