Introduction: Arduino Red Carpet Entrance

Red Carpet Entrance

This project helps you create a grand entrance. It detects you walking in and plays an entrance song. Walk into the room with your favorite starwars song being played for you. You will also need to install the tone library found at:
http://rogue-code.googlecode.com/files/Arduino-Library-Tone.zip

For Help installing libraries go to:
http://code.google.com/p/rogue-code/wiki/InstallingArduinoLibraries

Components Needed:

1x Speaker
1x Arduino
1x Bread Board
1x IR Reciever
1x 470 Ohm Resistor
1x 220 or 100 Ohm Resistor
Wires

Components can be found at http://egrobotics.com/store/
This Project uses and Arduino Board and IR Add-on Kit
