Design with HW-504 Joystick in Cirkit DesignerThe HW-504 Joystick is a versatile input device designed for controlling movement in a wide range of applications. It features dual-axis motion (X and Y axes) and is often equipped with a push-button for additional functionality. This joystick is commonly used in robotics, gaming controllers, remote-controlled vehicles, and other interactive systems requiring precise directional input.
Its compact design and ease of integration make it a popular choice for hobbyists and professionals alike. The HW-504 Joystick is compatible with microcontrollers such as Arduino, Raspberry Pi, and other development boards, making it an excellent choice for prototyping and DIY projects.
This circuit is a wireless joystick controller that uses an Arduino Nano to read analog signals from a KY-023 Dual Axis Joystick Module and transmits the data via an HC-05 Bluetooth Module. The system is powered by a 18650 Li-Ion battery with a rocker switch for power control.

This circuit features an Arduino UNO microcontroller connected to two servo motors and a KY-023 dual-axis joystick module. The joystick provides two analog inputs to control the position of the servos, with the potential for a button input from the joystick as well. The servos are powered by the Arduino's 5V output, and their movement is controlled by PWM signals from the Arduino's digital pins.

This circuit features an Arduino UNO R4 WiFi microcontroller interfaced with a KY-023 Dual Axis Joystick Module and three pushbuttons, each connected through a 200-ohm resistor. The Arduino reads the joystick and button states, processes the data, and sends it via WiFi UDP to a specified host, while also controlling an LED matrix for visual feedback.

This circuit features an Arduino Nano interfaced with a KY-023 Dual Axis Joystick Module for analog input, and an NRF24L01 module for wireless communication. The joystick provides x and y-axis control signals to the Arduino's analog inputs and a switch signal to a digital input, while the NRF24L01 enables the Arduino to communicate with other devices wirelessly. The 2x 18650 batteries supply power to the Arduino, which in turn powers the joystick and the NRF24L01 module.
Open Project in Cirkit DesignerThe HW-504 Joystick typically has 5 pins. The table below describes each pin:
| Pin | Label | Description |
|---|---|---|
| 1 | GND | Ground connection |
| 2 | +5V | Power supply (3.3V to 5V) |
| 3 | VRx | Analog output for X-axis movement |
| 4 | VRy | Analog output for Y-axis movement |
| 5 | SW | Digital output for push-button (Active LOW) |
+5V pin to the 5V output of your microcontroller and the GND pin to ground.VRx and VRy pins to the analog input pins of your microcontroller to read the X and Y axis values.SW pin to a digital input pin of your microcontroller. Use a pull-up resistor if necessary, as the button output is active LOW.Below is an example of how to interface the HW-504 Joystick with an Arduino UNO:
// Define pin connections
const int VRxPin = A0; // X-axis connected to analog pin A0
const int VRyPin = A1; // Y-axis connected to analog pin A1
const int SWPin = 2; // Push-button connected to digital pin 2
void setup() {
// Initialize serial communication for debugging
Serial.begin(9600);
// Configure the push-button pin as input with internal pull-up resistor
pinMode(SWPin, INPUT_PULLUP);
}
void loop() {
// Read the X and Y axis values (0 to 1023 for 10-bit ADC)
int xValue = analogRead(VRxPin);
int yValue = analogRead(VRyPin);
// Read the push-button state (LOW when pressed)
bool buttonState = digitalRead(SWPin) == LOW;
// Print the joystick values to the Serial Monitor
Serial.print("X: ");
Serial.print(xValue);
Serial.print(" | Y: ");
Serial.print(yValue);
Serial.print(" | Button: ");
Serial.println(buttonState ? "Pressed" : "Released");
// Add a small delay for stability
delay(100);
}

Q1: Can I use the HW-504 Joystick with a 3.3V microcontroller?
A1: Yes, the joystick operates at 3.3V to 5V. Ensure the microcontroller's ADC can read the voltage range.
Q2: How do I extend the joystick's lifespan?
A2: Avoid applying excessive force or rapid, repetitive movements. Store the joystick in a dry, dust-free environment.
Q3: Can I use the joystick for PWM motor control?
A3: Yes, you can map the analog output values to PWM signals to control motor speed and direction.
Q4: What is the resolution of the joystick's analog output?
A4: The resolution depends on the microcontroller's ADC. For example, an Arduino UNO has a 10-bit ADC, providing values from 0 to 1023.
