In this project we are going to build a simple Ohm Meter using Arduino. The basic principle behind this project is a Voltage Divider Network.
In this Project we are going to build a circuit used to measure unknown resistance. When we connect any resistor in the breadboard circuit the exact value of the resistor is displayed in the 16x2 LCD. This is done by utilizing the ADC feature of the Arduino and the voltage divider concept to measure the resistance with reduced errors. Now-a-days we use multimeter with range selector switches to find the unknown resistance which will consume time, so we also introduced Auto ranging feature to reduce the manual ranging functions by implementing logics in coding and hardware which is discussed below.

circuit is really simple. All you need is an Arduino, the resistor you want to measure, and another resistor with a known value. We’ll set up a voltage divider with the known and unknown resistors.
