creating phone app (development)

The custom phone app is created using app inventor. Desired elements are arrange onto the screen and then functions are programmed using block programming. 

The first screen design contains an introductory page where the name of the subject, name of student, name of advisor and related information is written. This screen functions as a front page for the application

Screen 2 is designed as the main screen where the quad copter controller user interface is put together. The functions and buttons emulate a standard RC transmitter where commands are sent to manipulate the throttle, rudder, yaw and pitch of the quad copter. However additional buttons are integrated to control the sensitivity of the throttle control and also to set the flight modes of the quad copter. In addition to that another button is set to simulate arming sequence of the transmitter to the quad copter. Furthermore one more button is designated to start Bluetooth connection with the interconnect circuit.
