I am looking to start a personal project but im not sure what board I should get. I dont want to reveal too much what the project is but I know that i will need a board that can read an input of a resistance and have an output of a voltage.
You're not giving us much info to go off of, but the Arduino Uno is a great board for beginners.
No Arduino can directly measure resistance (or current). You will need external circuitry to measure resistance. A simple voltage divider may be all you need, but without knowing more we can't say.
