Harp laser group

Our project is about the Laser Harp : our goal is to play music with lasers.
First, we wanted to transmit a sound from the laser, to the photodiode and finally to the speaker.
Then, we wanted to transmit music thanks to a mobile phone. We only had to plug it into the laser ; and we could hear the music which was emitted by the speaker.
Finally, we introduced the "Arduino chip" ; a programming chip. Thanks to it, we will be able to play differents tones.
