What is the Harp?
In old ages, Harp was an instrument that you only found in formal parties and in castle halls, it was originated in west Europe to serve this purpose.
It’s an instrument that contains 8 to 32 tight strings that are plucked to generate sounds.



The Laser Harp
The Laser Harp was founded in informal parties with electric instruments and sounds.



First Implementation
Components:
Arduino UNO 



First Implementation
Components:
Ultrasonic sensors



First Implementation
Components:
Laser



First Implementation
Components:
Servo Motor with mirror



First Implementation
Components:
Speaker



First Implementation
At the beginning we’ve build the project as a single light source with servo motor to reflect the light using a mirror.



First Implementation
Problems:
Laser beams
Sound system


Second Implementation
Components:
Arduino Mega 




Second Implementation
Components:
Mp3 Module & SD Card




Second Implementation
Components:
Compact Disk (CD)




Second Implementation
To split the beams uniformly we used a CD, with the right angle we focused two lasers to generate 8 beams.
Then we put each ultrasonic in the direction of the beam.




Second Implementation



Second Implementation



Second Implementation
Problems:
Lighting 
Lost Feature 
Laser Charging


Future Work (Laser Harp Game)
The Game is consist of a screen and two players (two harps), the game can find out who finished the displayed symphony first.



Conclusion
We started this semester with no practical knowledge, and the output was very pleasing, now we are capable of building useful Arduino base projects, maybe we didn’t end up with the best desired result, but we proud of what we accomplish.
