Tah is an open source development board that helps you create your own projects that can connect to your smart phone, laptop, or desktop via Bluetooth low energy.
This powerful combination allows Arduino applications to be controlled directly using your smartphone -- your phone's built-in accelerometer, gyroscope, and other sensors can directly trigger events in the physical world!
Tah is a LEGO block for enabling the Internet of Things.
Tah uses an onboard ATmega 32u4, similar to the Arduino Leonardo. This is major -- it means that everything you know about programming an Arduino, even the Arduino IDE, can be applied directly to Tah so you can start making amazing things right away.
ATmega32u4 — the microcontroller at the heart of Tah — has onboard USB 2.0 support, that is used to directly program the Tah without having to use a USB-to-Serial converter. Tah can also act as a USB human interface device (HID), which enables you to create your own keyboard, mouse, joystick, or other input devices, all without the need for installing special software on the host computer. If you want to create a new smarter custom keyboard that communicates with your smartphone, you need not look beyond the Tah. We've already made sample applications that allow you to control your PC, Mac, Linux, PlayStation and Xbox (coming soon) without ever needing to write any code for those platforms — all you need to do is program your Tah board and make a smartphone app, for which we've also provided open source examples for both iOS and Android to get you started.
