: Moving mechanical arms or sliders remotely.

: Create a new Template (e.g., "Robot Controller"). Configure Datastreams : Go to Datastreams and add a new Virtual Pin . Name it "Joystick". Choose a pin, for example, V1 . Set the data type to Integer or Double . Add the Widget : Go to the Web Dashboard or Mobile Dashboard . Drag and drop the Joystick widget.

Typically mapped to left-right movement or motor direction.

Name it Joystick_XY . Choose an available Virtual Pin (e.g., V1 ). Set the data type to String or Integer (Blynk handles array structures gracefully over strings/vectors).

: If the response feels laggy, ensure your void loop() is completely clean of delay() functions. Only Blynk.run() should be present.

: When enabled, the joystick handle automatically snaps back to the center position (0,0 or mid-range) when released. Rotate on Tilt : Automatically aligns the

Use the 2D plane to mix red and blue intensities on an RGB LED strip.

: Assigns X and Y to two different Virtual Pins. This is useful if you want to trigger independent actions that aren't strictly related to 2D movement. 2. Sensitivity and Write Interval
