I am trying to build an air/Fuel ratio led bar for my car. I found this writeup on how to do it. only problem is from my understanding it only reads 0-1v. I want 0-5v. How would I acomplish this?

thanks for your help

I just had a brief look at the circuit but it looks like a well placed voltage divider network should do the trick.
