Re: LED polarity

Thanks for that,

for some reason that I can't quite fathom I can't actually find that bit of text on the site, 
on the http://www.sequentix.com/build/cnst-switches.htm Colin does speak about the 
LED's but not as you've quoted. Anyway I was being unclear as I'm actually still on the 
regular LED with just the 2 legs, square pad -, circle pad + ?

Thanks again, 

Peter.
