WebHow this ohmmeter circuit works is that the 2 resistors in series form a voltage divider circuit. One end of the resistor pair is hooked up to 5V and the other end is hooked up to ground. The 5 volts that the Arduino provides gets divided up between the 2 resistors, depending on the value of the 2 resistors. WebOhmmeters are available in two forms i.e. the digital ohmmeter and the analogue ohmmeter. The digital ohmmeter displays the value of unknown resistance digitally, in the form of numeric digits. And the analogue ohmmeter displaces the value through a moving needed on a marked scale. fisher co2 regulator
