Went to home depot and found a very help person who was knowledgeable in electronics.  I have decided to use an extension cord as the backbone of my non-invasive device.  I will plug both the power source of the Arduino and the washing machine into the extension cord, then open up the extension cord to read the voltage of the washing machine. I am working and talking to kyle about different technique with resistors to bring the voltage down to a readable amount and then using the Arduino’s built in 0-5V reader to read the voltage.   Began working with online bread board and Arduino simulators to begin testing.
