Arduino Musical Instruments!

In two days, we created a musical instrument with Arduinos.  For the majority of us, it was the very first time we worked with circuits and had to do both hardware and software design.  Below are our presentations and demos of our projects.  Congratulations to Arjun and Jeffrey for their "Air Drums" and Nathan and Annie C for their "Octopus" instruments which earned them a tie for both the Faculty Choice and People's Choice recognition. Sarah, Annie M., and Jenny received an Honorable Mention.

Roland and Savannah

Soundboard Plus: Preset songs/tunes already on soundboard for you to enjoy.

Nathan and Annie - Faculty and People's Choice Awards

Octopus - Multiple buttons with respective notes when pressed, the lower half of the notes activate the Red Light, and the higher half activate the Blue Light. Pressing both black and white will play G. A button will playback what was previously played. Pressing the record button at the same time as the yellow will play the recording backwards.

Pianox7 - Press buttons to play music

Josh and Eric

Heptagonal piano - It uses the seven basic keys and formatting of a piano so kinds can learn to play simple tunes easily

Jeffrey and Arjun - *Faculty and People's Choice Awards

Air Drums - The air drums use proximity sensors to detect hand motion that is essential for playing the instrument. When a proximity sensor detects something, a note is played. The five sensors play different frequencies of sound. The five buttons on the arduino help "tune" the drums by changing the frequency of the sound depending on the distance away from the proximity sensor.

It's Light! - active using light/ adjust amount of light

Elizabeth and Irene

Irenabeth - By moving your hand closer to the sensor, more lights will light up and the note goes higher.
