In this project, we aim to use an Arduino board and a joystick to control either the position of a servo motor or the brightness of an LED. The Arduino board is a microcontroller that can be programmed to perform various tasks based on inputs it receives. The joystick provides analog inputs to the Arduino, which are then processed and translated into commands that control the servo motor or LED.

For controlling the servo motor, the joystick inputs are used to determine the angle at which the servo should be set. The servo will rotate to the specified angle when it receives a command from the Arduino. This allows us to control the position of the servo in real-time based on the inputs from the joystick.

For controlling the LED, the joystick inputs are used to determine the brightness of the LED. The brighter the LED, the higher the joystick input value. The Arduino uses these inputs to adjust the brightness of the LED in real-time based on the joystick inputs.

Overall, this project provides a hands-on introduction to physical computing and microcontroller programming. It demonstrates how easy it is to control physical devices with an Arduino board and a joystick, and provides a foundation for further exploration and experimentation.
