Connect to the Arduino board (or any other microcontroller) by using a Bluetooth SPP module like BlueSMiRF, HC-05, HC-06, BTM-222, etc.
Easy build the interface according to your project need: add buttons, sliders, LEDs, etc. Use accelerometer sensor for controlling the steering of an RC car, or for tilting a drone. Use plots to display real-time data from sensors.
You can export interface file and import on another device.
RoboRemoBT is cheaper version of RoboRemo, for those who need only Bluetooth SPP connectivity. Other functions are the same. If you think that you will need other connectivity as well in the future, we recommend the RoboRemo app: https://play.google.com/store/apps/details?id=com.hardcodedjoy.roboremo Please note that upgrading from RoboRemoBT to RoboRemo by paying the difference is NOT possible.
