I've built a model of an ancient temple (think Indiana Jones) that has a rolling door that opens or closes based on the direction of the joystick. I would like to add a sound effect of a stone door rolling but I'm having trouble incorporating this sound effect into my model when using the joystick (perhaps because I'm using a While statement. When I add the DoorRoll.wav to my joystick operation the door refuses to open and the SFX hang the program. Other SFX work when various buttons are pushed so I know it's a coding issue.
I'm using an Arduino Mega with the tmrpcm library. The sound effects are tested and work in other configurations but I cannot attach this sound effect to the action of the joystick with success. Any thoughts would be appreciated.
As I said, are other elements on the model but, to keep this post simple, I have whittled down the code to just include what's necessary for the door to operate but I'm also attaching the complete code for the other functions of the model (Buttons, LED's, LCD screen, etc.) if you want to see the full code.
