Hi , In a project ive been working on i need to read some 0-5v analog signals I have been doing this with just a voltage devider but only just realised that this will be causing the car which this is wired into to get lower signal reads that it should be .I need a way to solve this problem my first thought was an external adc but that looks as if it could get complicated is there a way i can do this with a transistor or an op amp so as not to put any load on the cars curcuit ? I seem to remember seeing something along these lines. If that isnt possible or you kow a better way please let me know , any help is appreciated .
I tried running my code on a 5v arduino how ever it ran way to slow to do what i want , the speed difference between an arduino uno and a teensy 3.1 is increadible
