Discharge a fully charged Lithium-Ion cell through a resistor while measuring the current flowing through the resistor to calculate capacity
A very simple but useful device for your lab.
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.
