We interact with a lot of devices everyday. Almost all of these can be made smarter by bringing a smartphone and Tah together. Tah is a Bluetooth 4.0 enabled development platform that is compatible with the Arduino.
The Tah app lets you control Tah's GPIO pins using our ArdSCL protocol in digital, analog and PWM modes. This app gives you the full power over GPIO acquisition by letting you read data from Tah's analog pins in real time.
You need the Tah board to be able to use this app. Get your Tah here: tah.io/get.
