Summary of the Circuit

This circuit is designed to interface an Arduino UNO with two servo motors and a KY-023 Dual Axis Joystick Module. The Arduino UNO acts as the central controller, reading inputs from the joystick and controlling the position of the servo motors accordingly. The joystick provides two axes of control and a pushbutton switch, which can be used for various interactive applications. The servo motors are powered by the Arduino and receive pulse width modulation (PWM) signals to set their positions.

Component List

Arduino UNO

• Description: A microcontroller board based on the ATmega328P.
• Purpose: Acts as the central processing unit of the circuit, reading joystick inputs and controlling servo positions.

Servo (x2)

• Description: A rotary actuator or linear actuator that allows for precise control of angular or linear position.
• Purpose: Responds to PWM signals from the Arduino to move to desired positions.

KY-023 Dual Axis Joystick Module

• Description: A joystick module with two potentiometers (one for each axis) and a pushbutton switch.
• Purpose: Provides user input to the Arduino for controlling the servos.
