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 directly from the Arduino's 5V output and receive pulse width modulation (PWM) signals to set their positions.

Documented Code

Arduino UNO Code (sketch.ino)

void setup() {
  // put your setup code here, to run once:

}

void loop() {
  // put your main code here, to run repeatedly:

}

This code template provides the basic structure for an Arduino sketch, with setup() function to initialize settings once and loop() function to run the main code repeatedly. The user is expected to fill in the logic for reading the joystick inputs and controlling the servo motors within these functions.
