Summary of Tissue Box Guitar – Light Strings using Arduino
This project transforms a wooden tissue box into an interactive musical instrument. When a person approaches, an ultrasonic sensor triggers a servo to lift a shelf revealing LEDs and LDRs that light up guitar strings. The system plays corresponding guitar sounds from a WAV file stored on an SD card via a Wave Shield, controlled by an Arduino Uno.
Parts used in the Tissue Box Guitar:
- Arduino Uno
- Adafruit Wave Shield
- Servo motor
- LDR (Light Dependent Resistor)
- Resistors (1k Ohm)
- LED
- Wires
- Wooden tissue box
- SD card with .Wav files
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
Step 1: Building Box
i made this wooden tissue box
Step 2: 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.

-
How does the tissue box detect when someone is nearby?
An ultrasonic sensor placed on the front side of the box detects people approaching. -
What component lifts the shelf to reveal the lights?
A servo motor receives an order from the ultrasonic sensor to push the bottom shelf up. -
Where should the wiring be connected for this project?
All wiring must be made on the Wave Shield rather than directly on the Arduino. -
How are the guitar sounds generated in this project?
Guitar sounds are played using .Wav files installed on the Wave Shield memory card. -
What is the function of the LDRs and LEDs in the box?
LEDs are placed under the LDRs so that when the shelf lifts, the light becomes effective on the sensors. -
Can other sounds be used instead of guitar strings?
Yes, you can use any .Wav file of anything else you like instead of guitar strings. -
Which pins are defined for the trigger and echo functions?
The code defines Trigger Pin as 7 and Echo Pin as 6.
