In this project, we will show how you can build an ohmmeter using an arduino.
An ohmmeter is a device that can measure resistance.
Most of the times now, ohmmeters aren’t standalone devices but appear as one of type of measuring device amongst many in a multimeter. An advanced multimeter, today, would have an ohmmeter, voltmeter, ammeter, capacitance meter, continuity tester, and possibly a temperature sensor. For this circuit, we are only going to build an ohmmeter, as to measure resistance.
Using the correct hardware interface and uploaded code, we can turn the arduino into a device that can measure resistance.
- 1KΩ resistor
- Resistor (whose value you want to measure)
These are all the parts which you will need. The circuit is very basic, as you will see below.
The circuit schematic for the ohmmeter using an arduino is shown below.
