Good evening all from California.
I have connected my Charlieplexed LoL shield (working) on top of the Spectrum Shield (Sparkfun) onto an Arduino Leonardo. I also have a Uno and Duemilenovo (sp?).
I have just assumed that someone has developed a sketch which, when the shields are coupled, one could get a "way cool" VU meter. I've searched for hours and have come up blank.
Can anyone point me towards a working sketch? Instructables looks interesting but it doesn't include the Spectrum Shield. I believe someone has already tackled this project but where is it?
Kindest regards for your help.
