🐪 Tutorial 22 - Joystick Module

The Joystick Module is a simple input device that allows users to control movement in two dimensions by manipulating a small joystick. It typically consists of two potentiometers that measure the position of the joystick in the x and y directions, as well as a push button that can be used for additional input.

The Joystick Module is commonly used in electronic projects, robotics, and gaming applications to provide a simple and intuitive way for users to control movement or interact with virtual environments. It can be connected to a microcontroller or other device using a variety of interfaces, including analog or digital inputs.

In addition to its use as a control input device, the Joystick Module can also be used for other applications such as sensing or measuring motion or position in two dimensions.

Overall, the Joystick Module is a versatile and easy-to-use input device that provides a simple and intuitive way for users to control movement or interact with electronic devices. Its low cost and compatibility with a wide range of microcontrollers and interfaces make it a popular choice for hobbyists and professionals alike.
