RE: Re: SOM1 relay board switching sound.

["Ian B" <Ian@xxxxxxx>]

Gut reaction here is this would be another module. There are no pins left
on
the standard PIC with all the relay board terminals etc. so the only way
of
communicating would be via serial. This would point towards a
programmable
keypad of sorts.
