This a connected circuit of a joystick, Servo Motor and passive buzzer. The Servo and buzzer are both controlled by the joystick. So, if the joystick is moved down to the left (where Y is at its max and X is at its minimum) the servo will increase in angle until its maximum of 180 degrees which will then set off the buzzer if the joystick is continually held in this position. Then the opposite is true for when the joystick is moved to the top right (when X is max and Y is minimum). So, the servo instead decreases in angle and then the buzzer will be triggered if the joystick is held over to that section continually.
