relay_atten
arduino based relay (stereo) volume control. each bit is assigned a 'stage' in the attenuator, each one being half the previous so that the binary 0, 1 stuff all works out ;)
those are latching relays and they need extra complexity to support them (one voltage latches one way, reverse the voltage and it latches the other way). the thing you have to remember is to REMOVE voltage after 50ms or so.
there is a bargraph led chip for debug use, so I can spy on the bus ;)
this is running a variant of my VoluMaster(tm) code base.
plans to be released once testing and development is complete.
