Making your own test equipment with an Arduino is always an interesting journey with analogue and digital electronics - and one example of this is an Ohm meter (to measure values of resistance) described by Praveen from Circuits Today.
His meter has an interesting auto-ranging input, which helps reduce the level of inaccuracy greatly. This could be improved even more with the use of very low tolerance resistors as well.
The explanation of operation is quite interesting, so for more information visit the project's website. And for more, we're on facebook, Google+, and twitter - so follow us for news and product updates as well.
Looking for a rapid-use LCD for your Arduino or compatible projects such as the ohm meter above? Save time and move forward with the Freetronics LCD & Keypad shield which contains a bright 16x2 character LCD and five buttons that can be read from only one analogue input pin:
