You can configure the output range in the Blynk app. Standard configurations use 0 to 255 for standard PWM motor speeds, or -100 to 100 for directional control with a central zero point. Two Modes:
By default, the joystick operates in "Merge" mode, sending both

The app sends these coordinate values to the Blynk Cloud Server via Wi-Fi or cellular data.

: Automatically resets values to zero (or mid-point) when released.
Unlike individual sliders, the joystick merges these axes into a single fluid input. This allows for intuitive vector mapping, which is essential for differential steering in robotics. Hardware and Software Requirements To build a project using the Blynk Joystick, you will need: Hardware Components
Allows users to map the minimum and maximum output values directly within the app interface (e.g., 0 to 255 or -100 to 100 ).
