Behavior

  • One of the most common dashboard widgets.
  • Can be styled as large telemetry tiles.
  • Often paired with charts and gauges showing the same signal.

Firmware contract

Just publish a value with Blynk.virtualWrite(Vx, value).

On the app side this widget snaps to the 8-column square grid and uses both resizing. Its raw type is VALUE_DISPLAY and the matching icon token in the app is textformat.123.

Pin support: A configured pin is required before the widget becomes meaningful.

Transmission: Payload format depends on the widget type and the selected pinType.

Allowed pin families

Bound to the configured pinType and limited by how the current app/connector serialize the widget payload.

Transport path

Payload leaves the canvas through the dashboard transport and lands on the selected virtual, digital or analog endpoint.

Operational limits

Server-side behavior may still depend on board library support and project policy.

Configuration surface

  • Color, label and position are stored in the dashboard profile.
  • Use the app-side widget config sheet to tune behavior per widget type.

Limits and caveats

  • Server-side behavior may still depend on board library support and project policy.

Firmware example

A minimal pattern that matches how this widget usually talks to the board.

value-display.ino
void loop() {  float temp = readTemp();  Blynk.virtualWrite(V4, temp);}
