Well, the entire project isn't invisible - however a very important part of it is! Created by Instructables user "musictechbolivoa", the harp strings' electronic equivalent is a row of infra-red transmitting and receiving LEDs monitored by an Arduino. To play the harp it's a simple matter of the user breaking the infra-red beams as if they were playing the strings, and the Arduino then sends the data back to a PC via a MIDI interface. Watch the following video for a good musical demonstration:
You have to hand it to the creator, they've certainly used some imagination and created a simple yet fun device. However you don't need to have a specific MIDI shield, there's links to software to allow connection via the Arduino's USB. For complete instructions, visit the project Instructable. And for more, we're on twitter and Google+, so follow us for news and product updates as well.
Have you been reading about Arduino and the types of projects created, but not sure where to start? Then order one our Experimenter's Kit for Arduino:
The package includes a wide variety of parts, sensors and modules including: a servo motor, lights, buttons, switches, sound, sensors, breadboard, wires and more. Furthermore a Freetronics Eleven Arduino-compatible board is included to make this an extensive hobby experimenter, inventor and starter kit.
However we don't leave you alone to figure it all out, included is a great project and instruction booklet, plus access to a supporting web page and software examples. In other words - this is everything you need to get started for a fun range of electronics and Arduino related projects! So to get started or for more information and to order, check out the product page.
