Electronic building blocks Dual PS2 game joystick button module JoyStick compatible with  R3

Thanks to the selfless sharing of the user Phoenix, the following test code is written for him, suitable for testing a variety of rocker or button code. Does not differentiate the board. IDE board with 1.8.6. If the latest update is not tested)

//This code is provided by phoenix.
// Only joysticks and buttons on all interfaces are tested.
//Only test the rocker and buttons on all interfaces.

void setup(void)
{
Serial.begin(9600); // Set the serial port communication rate to 9600 baud
for ( int i = 0;  i<=13;  i++)// Define the button position
{
pinMode(i,INPUT_PULLUP);
digitalWrite(i, 1);
}
}

void loop(void)

//******************* joystick position judgment, from port to port from 0-13; A1-A5(14-20)

Serial.print("=");
Serial.print(analogRead(i)); // Read the value of rocker X axis, serial port display
