I was able to resolve the audio issue. I had to change it from startPlayingFile to playFullFile and the audio files started to play when I touched specific spots on the display!

For now I am going with the rectangle boxes with the text inside and get the audio playing with these boxes.

The next revision of this device will include the following:

1. Actual images instead of text.

2. Connect a battery to both the Arduino devices to work without USB power.

3. Enable a screen time out to save power.

4. Get the accelerometer to detect when the device is picked up and "wake" the screen up.

5. Enable the Ultrasonic Sensor display on the LCD, the distance it is from an object.

I am going to submit my completed project now!

Two things I would look at are the hardware that you are using as well as the libraries that are used. I have found in some instances when using multiple devices connected to an Arduino board that the libraries that are created for each device could conflict with each other, specifically with how the lib is configuring the IO ports.

Do you get any error listed in the Arduino IDE console window when this event is seen?

Also, you have some serial print statements in the code, so are you watching these to see where the code may be getting hung up at?

Do you still see the issue if you taking out the musicPlayer statements and just maybe print out a note indicating that a touch event occurred?

What Arduino board are you using?

Hi Rob,

You could try adding an infinite loop after you print "Touch" to see if there is any issue before that [e.g. while(1).... ]. Then move that loop and/or add other serial.print statements to see how far you get and which bit crashes the system.

There isn't anything after your first if statement ...

not sure what happens there?

For info, if you select your code and then use the >> action button, syntax highlighting and then C++, your post will format nicer. You can use the edit button to that effect rather than reposting.
