Egyptian startup Integreight offers a single Arduino shield to replace many add-on boards. 1Sheeld pairs the Arduino to a smartphone to tap its sensor and I/O capabilities.

1Sheeld adds a host of functionalities to your Arduino without having to buy as many shields. Once the board is connected to the Arduino it enables communication with a smartphone over Bluetooth.

A mobile app enables the Arduino to use the hardware capabilities of the phone. With a single add-on board the Arduino has access the phone's features such as a touchscreen, WiFi, GPS, gyroscope, accelerometer, microphone and speakers.

The app comes with a lot of shields preloaded such as a slider, a LED and a push button. Paying tribute to the open source community, Integreight says the entire product will be open source: the hardware, the firmware and the Android app. Once the source code is available people can start building their own shields and share them with others.

Because of the many possibilities 1Sheeld opens up, it's an excellent tool for prototyping. The libraries delivered by Integreight are very similar to Arduino libraries so when you're ready to swap out the virtual shield for a physical one you don't have to make a lot of modifications.

At the moment 1Sheeld is only available via the Kickstarter campaign Integreight is running. For $49 the board will be shipped to you in the spring of 2014. The campaign has blasted past its $10,000 goal on the first day. Now, with still 23 days to go and nearly a thousand backers pledging over $50,000, the 1Sheeld team is asking backers for ideas to spend the money on.
