Hi,
I'm working on a school project for a feedback system. We need audio feedback whenever a certain weight threshold is reached, like a buzz/beep/song etc.
I was wondering if there was a way for an Arduino to send an audio signal to a bluetooth earpiece once it recognizes that the threshold has been passed.
I know there is a way to do this working through an Android phone, but I was hoping for a non-smartphone solution.
Any suggestions?
