Apr 17, 2017 · Inexpensive commercial test-meters use a rotary switch to select the range used to measure an unknown resistance. You can do better by using the Arduino to connect each of a range of resistors, one at a time, and selecting the calculated value that corresponds to a measured voltage that's closest to 2.5 v. The Arduino input/output pins can then use a very low current to activate a transistor, which then turns a higher current on and off from the 5V pin directly (which is connected straight to the output of the on-board linear voltage regulator), to the device you want to control.
