Teyleten Robot Dual-axis XY Joystick Module PS2 Game Joystick Control Lever Sensor Game Controller Sensor Board Module KY-023 for Arduino Raspberry (5pcs)

The cross rocker is a bi-directional 10K resistor, as the rocker direction is different, the resistance value of the taps change with it. This module uses 5V power supply, the original state of the X,Y readout voltage is about 2.5V, when pressed with the direction of the arrow, the readout voltage value increases, the maximum to 5V; the arrow in the opposite direction, the readout voltage value decreases, the minimum is 0V.
