I want to know if I get sensor value from rapid iot prototyping kit to Arduino Uno via Bluetooth
Does this post make sense: Rapid IOT Bluetooth Connectivity Issue on Android
Sure you can get data from Rapid IoT to Arduino over bluetooth. High level steps:
If you would use the OOB application on Rapid IoT kit all the sensor data is already available over BLE, but you may want to custom your app according to yout needs.
In Rapid IoT studio there is also a very simple example project to control the Rapid IoT kit led over BLE. It is meant to be controlled by phone app, but you could very well control it via your Arduino board.
Regarding Arduino programming and available shield, I advise to look on Arduino site or Hackster.io for example.
