Instructable for Biaxial Joystick

What We are Doing

This project prints out the X and Y coordinates from a joystick on the serial monitor.

Hardware

• Joystick module
• Arduino ^*
• USB cable for Arduino
• Male-to-Male connector wires

^* This example is for an Arduino Uno.

Libraries

No libraries are required.

Wiring Diagram


Example Code

/*
 Pin 1 of the joystick to A0 of the Arduino.
 Pin 2 of the joystick to A1 of the Arduino.
 Pin 3 of the joystick to the 5V power source of the Arduino.
 Pin 4 of the joystick to one of the ground connections on the Arduino.
 */

void setup() {
  Serial.begin(9600);
}

void loop() {
  int joystickXValue = analogRead(A0);
  int joystickYValue = analogRead(A1);
  Serial.print("The X and Y coordinates are:");
  Serial.print(joystickXValue, DEC);
  Serial.print(",");
  Serial.println(joystickYValue, DEC);
  delay(500);
}

Making It Better

• Use the joystick to control a tethered vehicle.

• Use the joystick to remotely control a vehicle. There are a number of ways to add remote control. See the WCRS instructables on IR remote, IR transmitter, nRF2401L transceivers, 8266 transceivers, and RFM69HW transceivers.
