Visuino Key Work !!exclusive!!

Visuino is a visual programming environment for Arduino and compatible microcontrollers. Instead of writing C++ code, users connect functional blocks (components) via wires in a flowchart-style interface. "Keys" in Visuino can refer to physical input devices (keypads), computer keyboard interactions (during simulation), or property values (security keys). Understanding how to implement these is fundamental for creating interactive embedded systems.
