/serialKAW

using the Arduino's Analog-to-Digital converters to read out a Kill-A-Watt at very high resolution (70+ samples per cycle of AC)

Primary LanguagePython

serialKAW

Piggyback the Kill-A-Watt's opamp and feed them to the Arduino's ADCs, which are then read out and fired over serial to a python script for plotting

Here is a quick writeup: serialKAW: Serial readout of Kill-A-Watt

*please excuse the shotty looking soldering, i promise it works =P
