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.

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.

Step

Plus/minus incremental control with fixed step size. Can either send the absolute value or the delta.
