My joystick doesn't work

[tikulik]

I have Arduino UNO and i found some diy game joystick tutorial on YT
code:

// Arduino pin numbers
const int SW_pin = 2; // digital pin connected to switch output
const int X_pin = 14; // analog pin connected to X output
const int Y_pin = 15; // analog pin connected to Y output

void setup() {
pinMode(SW_pin, INPUT);
digitalWrite(SW_pin, HIGH);
Serial.begin(115200);
}

void loop() {
Serial.print("Switch: ");
Serial.print(digitalRead(SW_pin));
Serial.print("\n");
Serial.print("X-axis: ");
Serial.print(analogRead(X_pin));
Serial.print("\n");
Serial.print("Y-axis: ");
Serial.println(analogRead(Y_pin));
Serial.print("\n\n");
delay(500);
}

scheme:

can you help me? (video: How to connect and use an Analog Joystick with an Arduino - Tutorial - YouTube)

Measure the voltage on the vrx and vry control potentiometers with a DMM.

Do you see a 0 to 5v swing.

const int X_pin = 14; // analog pin connected to X output
const int Y_pin = 15; // analog pin connected to Y output

For documentation, use A0 and A1 as you are measuring voltages.

@tikulik

const int X_pin = 14; // analog pin connected to X output
const int Y_pin = 15; // analog pin connected to Y output

As @LarryD said. You should use A0 and A1 instead of writing 14 &15

@tikulik - Try this simulation. It has your code, and you can save it and change it as you feel. Press the green > button, then mouse-click on the four joystick directions.

can you help me?

Maybe. You never said what was wrong.
