Because the Joystick widget is so versatile, it has become a chameleon in the maker community. It wears many faces.
This paper presents the design, implementation, and evaluation of a remote joystick interface using the Blynk IoT platform to control microcontroller-based devices (e.g., robots, servos, and motor drivers). We describe hardware selection, firmware architecture, Blynk app configuration, communication considerations, latency and reliability testing, and example applications. Results demonstrate that Blynk provides a rapid, cross-platform method for implementing touch-based joystick control with acceptable responsiveness for low-to-moderate real-time control tasks. blynk joystick
