In this tutorial we will be attaching three pressure plates or button to an Arduino. When the pressure plate is activated the Arduino plays a .MP3 file.


Arduino Uno (+ usb cable)
Micro SD card (this stores the .MP3 files)
Sparkfun MP3 player shield (available for rent at the Interaction Station)
Pressure plates or buttons (available for rent at the Interaction Station)
An active speaker or headphones
MP3 files

Getting ready

Step 1:
Make sure you have downloaded the Arduino IDE for the uploading the code to the Arduino board. If you don't have it, please go to , click on your operating system followed by pressing the 'just download' button. Install the software on your computer, but don't open it yet! If it opens automatically, don't worry, just close it.
