When Blynk launched, its primary innovation was the drag-and-drop interface. It allowed users to build a GUI (Graphical User Interface) in minutes. The Joystick widget was the star of this show. It was intuitive. A child who couldn't write a line of C++ understood that pushing the digital stick forward made the wheels of their RC car turn.
