Brief

Tello Drone is an impressive and programmable drone perfect for education. You can easily learn programming languages such as Scratch, Python, and Swift. A simple GUI was implemented to control the drone movement, direction, angle, takeoff, land and camera. The above was done by getting the user input through a text box and by writing a call back functions for dedicated buttons.
