Like I should talk :smile: Peter; Thank you again for your input ----- HOW DO YOU FIND THIS STUFF? I haven't had a chance to go over the links you refer to, but they sound very helpfull! Bean; Think of the source as a violin played by a beginner (my daughter is learning :eyes: ) The sine waves vary from moment to moment but they may not be true to notes desired. Similarly, I am trying to determine when a stream of varying waves hit certain frequencies but I only have to denote when the frequency matches/ or does not match, a set of predetermined frequencies. I would be happy with a green led for hit and a red led for not true to data set. Thanks again, I'll need some time to absorb the files you mentioned ---------- End of Message ---------- You can view the post on-line at: http://forums.parallax.com/forums/default.aspx?f=7&p=1&m=170818#m171263 Need assistance?
