What is a joystick?
A joystick is an input device used to control X & Y dimensions of any control system to which it is applied. It varies values of the two potentiometers which control X & Y axis respectively and a switch underneath.
Pinout
1. Ground (GND) – this pin is used to provide a common ground connection for the other pins.
2. Power (VCC) – this pin is used to provide power to the joystick. The voltage required may vary, but it is typically 5 volts.
3. X-axis – this pin provides an analog signal that corresponds to the horizontal position of the joystick. Depending on the joystick, this pin may also be labeled as “VRX” or “AN0”.
4. Y-axis – this pin provides an analog signal that corresponds to the vertical position of the joystick. Depending on the joystick, this pin may also be labeled as “VRY” or “AN1”.
5. Button – Some joysticks may also have additional pins for buttons or other features.
Applications
Joysticks have a wide range of applications, including:
1. Video games – For flight simulators, racing games, and arcade-style games.
2. Robotics – To control robots, such as remote-controlled drones or robotic arms.
3. PAN/Tilt Applications – To control heavy machinery/Cameras, cranes or bulldozers.
4. AR/VR – Input devices for virtual reality systems.
5. Surgical Robots – To control medical equipment, such as surgical robots or prosthetic limbs.
6. Accessibility – Input devices for individuals with disabilities, allowing them to control computers or other electronic devices.
7. Simulator Controls – Flight simulators or driving simulators, to provide a more realistic and immersive experience.
