This device serves for accurate measurement of small resistances in the range of 0.1 ohm up to 50 ohms.
In this tutorial I am looking at using millis function in the code. Describing the advantages it has over using delay function.
I was looking for ways to teach students the basics of PLC and found the OpenPLC project. Opensource, free and uses the IEC 61131 standard.
