The Arduino half of the software relies heavily on [Oleg Maruzov’s] PTP/USB libraries to get things done, but the free Android control app is all [Manishi’s] creation.

Why Bluetooth? An Android app has been developed for easy control of the Reflowduino, and will even graph the temperature profile.

Arduino enthusiasts searching for a board that supports connection via Bluetooth rather than USB may be interested in the Z-duino Bluetooth Arduino board recently launched via Kickstarter.
