A vibration switch is connected between the audio board's pin 7 and ground and orientation does not matter.

A 10uF capactitor also connects pin 7 to ground, but be sure to put it in the right way: the shorter leg goes to ground (and is also marked with - signs) and the longer leg goes to pin 7.

Since we’re using pin 7 in this diagram, the corresponding audio file on the board should be named T07.WAV or T07.OGG. You can really use any pin though…just make sure the filename matches. It’s all explained in the Audio FX Board intro guide.

Connect a speaker to one or both of the outputs on the audio board.

Optionally connect a button or switch between Rst and Gnd on the audio board (helps with troubleshooting the vibration switch).
