Joystick
A dual-axis analog joystick for directional control — perfect for robot steering and game-like interfaces.
Overview
The analog joystick module consists of two potentiometers (X and Y axes) and an optional push button (SW). Each axis outputs an analog voltage from 0 to 5V, read as 0–1023 by the Arduino's ADC. Center position reads approximately 512 on each axis.
ArduinoStudio emits sensor-data events with X and Y values whenever the joystick is moved, making it easy to map joystick position to motor speed, servo angle, or LED brightness.

| Operating Voltage | 3.3 – 5V |
| Button | Momentary push (active LOW) |
Wiring Guide
| Joystick Pin | Arduino Pin |
|---|---|
| VCC | 5V |
| GND | GND |
| VRx | Analog pin (e.g., A0) — X axis |
| VRy | Analog pin (e.g., A1) — Y axis |
| SW | Digital pin (optional — button press) |
Usage in ArduinoStudio
Drag the Joystick component onto the canvas and assign two analog pins (X and Y). The component continuously reports position data. Use the X/Y values to:
- Control two motors for tank-style steering
- Move a servo on the X axis and another on Y (pan-tilt)
- Map joystick position to RGB LED color mixing
- Build a game controller interface
