Using this Mini Analog Joystick is easy. First, connect one side of each of the two 10KΩ potentiometers to the ground and the other side to a higher voltage. Then you can read the analog voltage from the middle. It offers a 50 - degree movement in both X and Y directions, which is great for getting precise control. When using it, make sure the connections are stable to avoid inaccurate readings. As for maintenance, if you feel the spring - back force is too strong or weak, you can replace the springs. Also, keep it clean from dust and debris to ensure its long - term performance.
