Apply this code to your Arduino.
#include <Joystick.h>
// Create the Joystick
Joystick_ Joystick;
int potival = 0; //define potis current value
void setup() {
// Serial.begin(9600); // start serial communication
pinMode(3,OUTPUT);
pinMode(7,INPUT_PULLUP);
pinMode(8,INPUT_PULLUP);
Joystick.begin(); // start up the joystick
}
void loop() {
int draw_btn = digitalRead(7);
potival = analogRead(1); // read out the analog pin 1 and save in varialbe potival
if( !draw_btn ){
Joystick.setXAxis(potival);
}else{
Joystick.setYAxis(potival);
}
delay(10); // delay
}
