Joystick Module X-Y

This is a joystick very similar to the ‘analog’ joysticks on PS2 (PlayStation 2) controllers. Directional movements are simply two potentiometers – one for each axis. Pots are ~10k each. This joystick also has a select button that is actuated when the joystick is pressed down. This is a Joystick module that has X,Y analog outputs and has a switch that detects button press. The joystick is made up of two passive potentio-meters (variable resistors) and a push button and therefore can be used at any standard voltage levels. Lots of robotic projects need a joystick. This module offers an affordable solution to that. The Joystick module is similar to analog joysticks found in gamepads. It is made by mounting two potentiometers at a 90 degrees angle. The potentiometers are connected to a short stick centered by springs. This module produces an output of around 2.5V from X and Y when it is in resting position. Moving the joystick will cause the output to vary from 0v to 5V depending on its direction. If you connect this module to a microcontroller, you can expect to read a value of around 512 in its resting position (expect small variations due to tiny imprecisions of the springs and mechanism) When you move the joystick you should see the values change from 0 to 1023 depending on its position.

Applications

• Joystick that can be interfaced with Arduino, Raspberry Pi, and other Microcontrollers and Embedded Boards
• Joystick for custom designed/experimental RC planes, RC Cars
• Joystick for CNC Machines or other industrial controls
• Electronic games pads similar to PlayStation.

Connection

Using the board to connect the joystick is reduced to the following pins:

• VCC – supply voltage (5 V).
• GND– ground of the system.
• VRx – the analog output for the vertical axis (in the middle position, the value is equal to half of the supply voltage VCC/2).
• VRy– Analog output for the horizontal axis (in the middle position, the value is equal to half of the supply voltage VCC/2).
• SW– Digital signal button, in case of activation, it reaches the value of the GND, deactivated – is in thefloating status – so you need to add a pulling-up resistor to power.

Attention!

Because of the few-procent tolerance of the resistors, the middle value may not be equal to half the supply voltage (VCC/2). The manufacturer recommends measuring the voltage in the middle position and writing a permanent, rigid value in the program.

The joystick is a device of low power. It must be connected only to the inputs of high input impedance, for example, the ports of the microcontroller. Do not connect the device to the elements consuming a relatively large current: LEDs, motors – as this will damage the system.
