This is the project used to identify and measure unknown resistance or capacitance. When we connect any resistor or capacitor in the breadboard circuit will find whether it is a resistor or capacitor and calculate the exact value of the resistance or capacitance and it is displayed in the 16x2 LCD.This is done by utilizing the ADC feature of the Arduino and the Auto ranging voltage divider concept to measure the resistance with reduced errors and RC charging circuit to develop the Capacitance meter.
