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 Remote app lets you control all remote-controlled appliances around you by turning your device into a universal remote controller. It takes minutes to sync your existing infrared remote controller with this app with an IR shield attached to the Tah board, and you can then use your iPhone or iPad to remotely control the appliance.
You need the Tah board to be able to use this app. Get your Tah here: tah.io/get.
