I have been trying to figure out how to test a diy oxygen sensor guage. The sensor's values range from 0-1volt. Here is a schematic of the guage

I am wondering what I can do to use the 7805's 5 volt output to give me different voltage outputs for the signal input.
I basically need to create a signal voltage of .450 volts. I have been trying to figure out what resistors, trimmers, etc to use but I am a noob. Truthfully only .450 volts is needed anything else will only give me estimates of the LEDs to voltage meaning.
Thanks.
