Keyestudio Micro bit Honeycomb PS2 Joystick Module

The keyestudio micro bit Honeycomb PS2 joystick module is fully compatible with micro bit control board. In the experiment, we connect the joystick module to the micro:bit control board using crocodile clip wire. There are 6 ports on the module, two GND ports are connected. When controlling it, we need to connect the VRx，VRy port to the analog port of the micro:bit control board, and the SW port to the digital port of the micro:bit control board. We can judge the working state of the joystick on the module by reading the two analog values and the high and low levels of a digital port.
Special Note: When testing the SW port function, for some products, we need connect a resistor to SW interface (connect to VCC port after connecting a resistor), the port function is valid; otherwise SW port is invalid.
