Setting Up a Simple Joystick on Arduino for Beginner!

This Tutorial Will Cover On HOW We Could Implement A Joystick Control System Into an Arduino From The Joystick Input.

Gather The Required Material:

From Amazon:

1. Joytick Module
2. Best Affordable Arduino (Elegoo Brand Distributions) Available High Quality
3. Jumper Wire

From Ebay Discount 1%-4% OFF:

1. Joystick Module
2. Best Affordable Arduino
3. Jumper Wire

Connection Instructions:

1. Connect the gnd of the joystick module to gnd pin of Arduino.
2. Connect the Vin or V+ of the joystick module to 5V pin of Arduino.
3. Connect the VRx of the joystick module to A0 pin of Arduino.
4. Connect the VRy of the joystick module to A1 pin of Arduino.
5. Connect the SW or Press of the joystick module to pin 2 of Arduino.

Program Code:

• Overall Code:

int VRx = A0;
int VRy = A1;
int SW = 2;

int xPosition = 0;
int yPosition = 0;
int SW_state = 0;
int mapX = 0;
int mapY = 0;

void setup() {
  Serial.begin(9600); 
  pinMode(VRx, INPUT);
  pinMode(VRy, INPUT);
  pinMode(SW, INPUT_PULLUP); 
}
void loop() {
  xPosition = analogRead(VRx);
  yPosition = analogRead(VRy);
  SW_state = digitalRead(SW);
  mapX = map(xPosition, 0, 1023, -100, 100);
  mapY = map(yPosition, 0, 1023, -100 100);
  
  Serial.print("X: " + String(mapX));
  Serial.print("\tY: " + String(mapY));
  Serial.println("\tButton: " + String(SW_state));
  delay(100);
}

• Explanation Code:

1. Initialize Variable For Arduino Pin:

int VRx = A0;  #Analog Input Variable For VRx
int VRy = A1;  #Analog Input Variable For VRy
int SW = 2;  #Digital Input Variable For Press Button 

2. Initialize Variable For Storing Arduino Internal Data:

int xPosition = 0; #Initialising Stored Variable For X-Movement 
int yPosition = 0; #Initialising Stored Variable For Y-Movement
int SW_state = 0; #Initialising Stored Variable For Press Reaction
int mapX = 0; #Initialising Stored Variable Of Output Value Of X After Mapping
int mapY = 0; #Initialising Stored Variable Of Ouptput Vale Of Y After Mapping

3. Startup Setup For Arduino With Pin Modes Initialized:

void setup() {
  Serial.begin(9600);  #Begin Arduino Serial Data
  pinMode(VRx, INPUT);  #Set VRx Pin as an Input 
  pinMode(VRy, INPUT);  #Set VRy Pin as an Input
  pinMode(SW, INPUT_PULLUP); #Set SW Pin as Input 
}

4. Loop Code That Would Run In Arduino, With The Given Serial Print Of Output From The Mapping:

void loop() {
  xPosition = analogRead(VRx); #Stored The Analog Input Data Into The Variable
  yPosition = analogRead(VRy); #----
  SW_state = digitalRead(SW); #Stored The Digital Input Data Into The Variable
  mapX = map(xPosition, 0, 1023, -100, 100); #Start Mapping The X-Value From a range of 0-1023 into range
  mapY = map(yPosition, 0, 1023, -100 100);  #of -100-100 (-100 as backward and 100 as frontward)
  
  Serial.print("X: " + String(mapX));  #Print The Stored Variable In Arduino Serial Data 
  Serial.print("\tY: " + String(mapY)); #-----
  Serial.println("\tButton: " + String(SW_state)); #------
  delay(100); #Slow Down The Serial Print Speed By Adding Delay of 100 ms 
}
