It is easy to build an Arduino Ohmmeter, there are many implementations on the web. However, the accuracy is not discussed thoroughly enough. Here we try to make it clear.
- Read our paper (or if you don’t have access, our pre-print) for theory, experiments and instructions.
- Use our on-line calculator to configure your Ohmmeter and to estimate accuracy.
- The source code is available here.
Take part in our on-line collaboration project to test Arduino Ohmmeters:

- Hints
- You can buy 1% tolerance resistors in webshops for a few cents/piece.
- 3k resistors can be built using three 1k resistors connected in series
