Although the Sunstar Back to the Future 1:18 DeLorean models are awesome on their own, I really wanted to hear sound bites from the movies and see some fire under the tire action every time I walked by my display case. Using the Arduino and Adarfruit Wave Shield, I can play music and quotes from the movies with the push of a button. In addition, I installed several LED lights underneath the models and hacked an Under-Cabinet Light so that it can be controlled by my Arduino. Not only does my setup play sound, LEDs light up the DeLorean from the corresponding clip. Right now my system plays 13 different clips taken from all three movies. The grand finale is a fully choreographed light show to the BTTF theme song! Check out my videos to see it in action!
This does not necessarily have to be used for BTTF model cars. You can use these same techniques to add lighting to any model car display case. Also, you can add sound clips from any tv show or movie to complement your particular model on display.
