Analog joystick has two variable resistors for two axis. Each variable resistor has three pins, two extreme pins are connected to Vcc (5v in our case) and ground. The center pin is the output pin. By measuring the voltage output of two variable resister from which the joystick is built, we can determine the position of stick in x and y axis.
