Open source practice researcher Catarina Mota and Will Byrd have created a special take on a piano using an Arduino Mega board - their Paper Piano Box. It is a piano with twelve keys, with the keyboard fashioned out of cardboard and copper tape - each key is a capacitive sensor read by the Arduino. Tones are generated with the Arduino tone library and up to five tones can be played simultaneously. Furthermore a visual rendition of the music is displayed using LEDs and light tubes. For more information, review the following video:
Catarina has made the Arduino sketch and notes available here. And we're on twitter and Google+, so follow us for news and product updates as well.
When your projects outgrow the normal Arduino-compatible boards, running out of program and flash memory space, or you're stacking on Ethernet and microSD shields, or all at once - it's time to upgrade to the Freetronics EtherMega:
Quite simple the EtherMega is the fully-loaded Arduino-compatible board on the market today. Apart from being completely Arduino Mega2560-compatible, it includes full Ethernet interface, a microSD card socket, full USB interface, optional Power-over-Ethernet support and still has a circuit prototyping area with extra I2C interface pins. So if your project is breaking the limits, upgrade to the EtherMega today.
