The recording module has its own button.
KISS. Don't need an Arduino.Use a double pole switch, one pole turns the play, the other pole turns on the motor.Unless you have periods of silence recorded and want them to stop while recording is running.You could also use a 9 volt regulator so that everything runs off the same 12V supply then you would only require one pole. Will need filtering around 9Volt reg.Tom.
