two-axis key joystick module through the use of PS2 rocker potentiometer, with (X, Y) 2-axis analog output, (Z) 1 button digital output. with the Arduino sensor expansion card it can produce a remote control and other interactive works. In addition, this product can be easily with the arduino expansion card and other standard interfaces, in the design of the X, Y, Z axis of the circuit are separate leads, the user can 3-pin ARDUINO special line really plug into the expansion card.
1. Input voltage: DC 3.3 V to 5 V
2. Output signal: the module special two-way analog output and a digital output interface, the output value matches (X, Y) biaxial offset, the type analog; keys that the user is on the z axis, his type is digital switch.
3. Arduino controller can be programmed, the sensor expansion card plug, complete with creative remote interactive working.
4. Cross joystick is a bi-directional 10K resistor, with the rocker in different directions, the tap resistance with the change. This module uses 5 V power supply, the original state of X, Y read voltage of 2.5 V or so, when pressed with the arrow direction, the read voltage value increases with the maximum to 5 V; arrows in the opposite direction press, read the voltage decreases, the minimum 0 V.
