In Experiment 6, we used Arduino to measure the voltage at port A5. By applying Ohm’s Law I = U / R, we can calculate the current flowing through a known resistor by measuring the voltage across it.In this experiment, we will learn how to use Arduino to create a simple current meter.1. Experiment Materials … Read more
