I'm new here and am gradually getting my head around programming the Arduino.
I am making an automotive project and would like to combine several items to produce a display on a 5 inch screen or possibly multiple smaller screens to show my cars AFR, RPM, TPS and MAP sensor inputs.
So far, I have completed the TPS section where the Arduino reads the input from a TPS connected to the throttle bracket on my carb and then displays the result as a percentage on a small 16x2 LCD screen.
The MAP sensor will be very similar to code.
The AFR will have to take an input voltage and then compare it to values in a table and then output the reading in a range from 9.0 - 20.8
The bit I am working on at the moment is looking to see how to convert the pulse signal from my HEI distributor and read it on the Arduino and convert it to an output between say 0 and 7000rpm. I have started to research this and it looks like using interrupts may be the way to go.
Has anyone had any experience of this and if so, could you possibly point me in the right direction in how I might go about achieving my desired results. I'm happy to look at links to pages where this has been done, videos, or posts to parts of code that I may be able to modify to suit my purpose.
Thank you in advance, any and all tips or advice greatly appreciated. Oh, and I am very new to this so it may take me a while to research any tips given to gain a good understanding of what is going on.
