I need to know how to make a circuit for my car to read the voltage off my Oxygen sensor. It puts out a voltage from about 0-1 volts. I want it to be a digital numerical LED display. It really only has to display in hundreths of a volt. I would assume it needs to be of a high resistance so it doesnt "steal" some of the signal going to the cars actual computer. Also it needs to update as quick as possible, realtime if possible. This is my first project and I have basic experience so keep it simple. I know how to make one in the bar display but want a numerical display is there an IC that will hook up to a 2 digit LED?
Thanks in advance.
