Hi,
I need to add a smal speaker to a project.
I know I will need some form of volume control, but am not too sure what to do.
Ideally I would like to control the volume "code wise" by having the Arduino up the volume in response to input either from a web page or from the LCD panel attached to the project box.
All I have at the moment is the speaker, no other hardware or software.
Could you please point me in the right direction (nicely) ...
Thanks as always,
kind regards,
jB

Re: Volume Control
The Adafruit WaveShield can do volume control in software. It is not really a great way to do it because you lose some resolution of the signal in the process. A better solution would be a "digital potentiometer". These can attenuate an audio signal under software control without serious degradation.
