Hi everyone. I am new here and trying to build a display for my motorcycle (vs1400).
What I have in mind is a display for the engine speed in rpm's along with with other displays for voltage and temperature.
My problem is with the tachometer.
I figure on using a timing circuit based on the 555 chip like this:

and a four digit display like the one at this site:

my question is, What do I need to do to get the display show me what I want?
I have been doing some research on the web when time permits but so far I have found no definitive answer to my question.
Any help is greatly appreciated. If you have only a small part of the puzzle please post. You may have the piece of information that solves this design problem.
Once I have a working unit, I intend to do a complete write up for anyone else who wishes to do something similar.
