Introduction: Tissue Box Guitar - Light Strings

Picture of Tissue Box Guitar - Light Strings
the idea of anything can be an instrumental music has been always in my mind so i made a wooden tissue box that i installed inside it a guitar of light strings 


Video:


equipments:

1 x Arduino Uno
1 x Adafruit Wave Shield 
1 x Servo
6 x LDR
12 x 1k Resistors
6 x LED
WIRES

Step 1: Building Box

Picture of Building Box

i made this wooden tissue box 

Step 2: Wiring

Picture of Wiring

we make the LDR wiring on a the top shelf of the box ... while the Led's are on the buttom shelf we place them under the LDR's directly to make the light effective on the LDR.

Ultrasonic Sensor we place it on the front side of the tissue box so it could be able to see when people comes close to it and give the servo the order to open the shelf here the servo pushes the shelf of the Led's up and they will be visible to the user !

P.S: ALL THE WIRING SHOULD BE MADE ON THE WAVE SHIELD NOT ON THE ARDUINO DIRECTLY.
i couldn't find a figure for the wave shield here  

for the sound all you have to do is to get a .Wav files of guitar strings ! or anything else you like ... and install them on the Waveshield Memory card.

Step 3: Coding

You need to install Softwareservo Library to your arduino because waveshield and Servo uses the same Timer in arduino .. but when you use Softwareservo library it all works well.

Happy Building

Great project! good luck!!!

What would to code look like if I didn't want to use the servo, and just use the LEDs and photo sensors? I'm still pretty new to Arduino so I'm just having trouble figuring it out.
