I'll read the information about openenergy.
I have one more question, in the next image
In this image we use a simple circuit and a protoboard with a variable resistor, we use a protoboard with a variable resistor, we use too three multimeters to measure
the current, voltage and resistence, so I was thinking, if I connect the wires to the multimeter to measure amperage to arduino, it will be possible to measure the current?, and if is possible, How I can write this into the program for the arduino?.
The actual measures with the multimeters are for example, in current is around to 12 mA or 14 mA, in voltage is 750 mV.
