- why you think it is useful for others and for you
General Description
Introduction:
The purpose of this project is to create an electrical harp composed of 7 lasers facing 7 detectors all connected to an Arduino with a speaker that will play a different song for each couple of lasers and detectors. We want to do this project because t s different than what we usually see as an Arduino project, and it can be interesting to enjoy building our own instrument with our own needs and desires.
Description:
The man principle is the following: when a detector detects a signal from the laser t s facing, noting happens, but when it doesn’t, that means someone put its finger on the « virtual laser chord » a song from an mp3 will be played with the right note. We are going to use a wood structure and we will try to make it have the shape of an actual hard. The deals to fx the lasers, detectors, the speaker, and the Arduino board on the Wood to make tone object like a real harp that you can take with you everywhere. We also want to implement an LCD screen that shows which note is being played when we turn on the harp. As a result, we are going to use everything we learned during lab 1, 3 and 4. Lab 3 because we are going to use a timer when we switch on the harp twang for the note to be played, lab 4 because we are going to use an ADC with the detector and the laser.
Hardware Design
Here you put everything related to hardware design:
- parts list
- electrical schematics (can also be taken from the Internet and from datasheets, eg http://www.captain.at/electronic-atmega16-mmc-schematic.png)
- signal diagrams
- simulation results
Software Design
Description of the application code (firmware):
- development environment (if any) (eg AVR Studio, CodeVisionAVR)
- 3rd-party libraries and sources (eg Procyon AVRlib)
- algorithms and structures you plan to implement
- (stage 3) sources and functions implemented
Results Obtained
What were the results obtained after the realization of your project.
Conclusions
Download
An archive (or more if necessary) with the files obtained as a result of the project: sources, schemes, etc. A README file, a ChangeLog, a build script and automatic copy on uC always make a good impression 
.
.
The files are uploaded to the wiki using the Add Images or other files facility. The namespace in which the files are uploaded is of the type :pm:prj20??:c? or :pm:prj20??:c?:student_name (if applicable). Example: Dumitru Alin, 331CC → :pm:prj2009:cc:dumitru_alin.
Journal
You can also have a journal section where the project assistant can track the progress of the project.
