Mains Frequency Meter 9600
mains-frequency-meter / README
A simple circuit and Arduino code to turn a moving coil meter into a mains frequency meter. As used for the artwork entitled "Time for Tea?": http://andrewback.net/works/Time-for-Tea The circuit and source code should be reasonably self-explanatory, but I'll add a few notes here in due course. Schematic documented using gEDA. No board layout has been completed as it was simple enough to construct on prototyping board. Copyright 2010-2011 Andrew Back.
