![]() ![]() As told earliar more than one Joystick can be interfaced to get more controls other than these basic four functions.Ĭonst int SW_pin = 2 // digital pin connected to switch outputĬonst int X_pin = A0 // analog pin connected to X outputĬonst int Y_pin = A1 // analog pin connected to Y output So this is how a normal Joystick can be converted into a Game Controller using Arduino Leonardo and can be used to play games having all the controls to move left, right, up and down. So as we move the joystick, the voltage value will change and the analog value at Analog pins A0 and A1 will also change. Each potentiometer gets 5v from the Arduino. The Joystick has two potentiometers inside it, one is for X-axis movement and another is for Y-axis movement. We can control the any game controls using this Joystick. Now you are ready to play with the joystick. Next check the ‘ Devices and Printers’ in your control panel, you will be able to see “ Arduino Leonardo” under devices section as shown in below image. Joystick also has a push button on top so this button (SW) is also read and if the button is pressed the value will be 0 then the command for “enter” is given.įinally burn the code into Arduino and connect the Arduino with computer. Similarly, the analog value of the VRY pin is read and if the value is 1023 then the command for “right” is given and if the value is 0 then the command for “left” is given. The analog value of the VRX pin is read and if the value is 1023 then the command for “up” is given and if the value is 0 then the command for “down” is given. const int X_pin and const int Y_pin respectively Next in below code, we have initialised X and Y axis of the Joystick module for Analog pin A0 and A1 respectively. This Arduino Joystick Game Controller requires connections between the Arduino and the Joystick as follows:Ĭomplete code with a demo video is given at the end here we are explaining few important part of it.įirstly, we need to initialize the keyboard library #include When the stick is moved, the voltage on each pin goes high or low depending on direction. So we have four directions of Joystick on two ADC outputs. Similarly, when it is moved along the vertical axis, the voltage at Ry pin changes. When joystick is moved along the horizontal axis, the voltage at Rx pin changes. When the Joystick is in standby, Rx and Ry act as voltage divider. So Rx and Ry are variable points to these pots. The mid points of these pots are driven out as Rx and Ry. Each axis of JOY STICK is mounted to a potentiometer or pot. This joystick module has two axes as you can see.
