Related widgets

Button

Momentary or toggle actuator that writes a single scalar to a virtual pin. The canvas renders live state; the board reacts through a BLYNK_WRITE handler.

Toggle

Sliding on/off switch for binary state. Same payload contract as Button in switch mode but with a toggle affordance.

Slider

Horizontal numeric range input with optional send-on-release. Debounces fast drags before writing to the pin.

Segmented Control

Compact index selector for modes or presets. Writes the selected segment index to the pin.
