ACS712 Current Sensor with Arduino - Measure AC and DC up to 30 amps

Using the ACS712 current sensor with Arduino, we can measure AC and DC current up to 30 amps. I used the 5 amp version here and tried to improve the measurement noise with a filter capacitor to get better readings.

This was using the 10 bit ADC on Uno. I will compare results when I receive a higher resolution external ADC.
