[2pcs]

Product performance:
1. Input voltage range: DC 3.3V to 5V
2. Output signal: the module special two-way analog output and a digital output interface, the output value corresponding to (X, Y) biaxial offset, the type of analog; keys that the user press the Z axis, Its type is digital switch.
3. Compatible With Arduino controller can be programmed, the sensor expansion board plug, complete with creative remote interactive works.
4. Cross joystick is a bi-directional 10K resistor, with the rocker in different directions, the tap resistance with the change. This module uses 5V power supply, the state of X, Y read voltage of 2.5V or so, when pressed with the arrow direction, the read voltage value increases with the maximum to 5V; arrows in the opposite direction to press, read the voltage decreases , The minimum is 0V.
Tutorial:
In the introduction of how to use, we first look at how it works, which we use it very helpful, there is a function of the following diagram:
In fact, this module is a potentiometer, x, y-dimensional data output port is read out the analog voltage. This figure does not draw the above z-dimensional data output, z-dimensional output only 0 and 1, can be achieved by a button. All in all, it is a combination of potentiometer and button. x, y dimension we received two analog ports to read their values, while the z-dimensional we are connected to the digital port, connected to the power and ground.
