For some audio boards I generally use a LM555 timer whose output drives a transistor and closes the switch contacts every xx minutes. For other audio boards I use a simple lever switch that closes the contacts when a coffin lid opens or a pop-up raises up. Lever switches are great.Thanks, a lot. Just purchased it and the audio boards also. What exactly did you use to trigger the audio on the audio boards?
