Control Servo motor using Joystick

In this Instructable, I are going to control a servo motor by using a joystick module. When the joystick moves in the horizontal direction, the servo will move towards right or left. Lets start this!

What we have here are the joystick module and the servo motor, the Joysticks or in some cases thumbstick are a great source of input for a project. Especially for robotics. this joystick module is similar to the ones the we find on a PS4 Controller. The X and Y axes are two ~10k potentiometers which control 2D movement by generating analog signals and also has a push button that could be used for special applications.

We will be using the servo as the components to control by joystick, servo motor has everything built-in a motor, a feedback circuit, and most important, a motor driver. It just needs one power line, one ground, and one control pin. or simply servo motors are great devices that can turn to a specified position.

COMPONENTS

SG90 SERVO

Arduino Board

Joystick module

BreadBoard

CIRCUIT DIAGRAM

The parts of this project is very easy to make. First, connect the joystick module with the uno. The connections for the joystick module and the Arduino are as follows:

Connect the pin X of the joystick to pin A0 on uno

Y pin to A1

WS to pin 2

GND to GND

5V to 5V

---

connect the black/brown wire to the GND

the red wire to 5V

 the orange/yellow one to pin 9

SOFTWARE

Before we work on our sketch, make sure to download the Arduino IDE for your specific operating system. I’ll leave a link to where you can download this software: https://www.arduino.cc/en/Main/Software

Arduino Sketch code for servo motor and joystick

Copy code here:

---

#include <Servo.h>
const int SW_pin = 2; 
const int X_pin = A0; 
const int Y_pin = A1; 
Servo myservo;  
int val;  
void setup() {
  myservo.attach(9); 
}
void loop() {
  val = analogRead(Y_pin);            
  val = map(val, 0, 1023, 0, 180);  
  myservo.write(val);       
  delay(15); 
}

Code Explanation
#include <Servo.h> included the library for the servo motor which will help us with making the code easier.
const int SW_pin = 2;
const int X_pin = A0;
const int Y_pin = A1;
initialized the pins we have connected the horizontal pins on the joystick module and also the signal pins on the servos
int val; variable to read the value from the analog pin(Y_pin)
myservo.attach(9); attaches the servo on pin 9 to the servo object
val = analogRead(Y_pin); reads the value of the Y_pin (value between 0 and 1023)
val = map(val, 0, 1023, 0, 180); scale it to use it with the servo (value between 0 and 180)
myservo.write(val);sets the servo position according to the scaled value
delay(15); delay time of the servo to get there.

Time to test if itds going to work, and here it is..

view diagram in fullsize so thats it! I hope that this little arduino project would help, thank you for stopping by, please follow me @pakganern
