ok, THIS is what I am working with for a current sensor. or will be when they arrive from china. I have never used one of these, so I have no idea how to interface it to an Arduino analog in.
The project is a DCC++ base station, and I am measuring the current going to the track. I just need help finding a circuit to interface it, and what formula in needed on the Arduino to get the amps being drawn.
Thanks in advance for whomever solves my mind from drawing a blank. :D
