Lesson 37 Star Wars

3178

Overview

In this lesson, we will make a star wars game based on the Processing and play the game with a PS2 joystick and a button connected to the Arduino UNO.


Components

- 1 * Arduino UNO

- 1 * USB Cable

- 1 * Button

- 1 * PS2 Joystick

- 1 * Breadboard

- Several jumper wires


Principle

The experiment consists of two parts: first, acquire the data from Arduino; second, process the data.

Play the Star Wars Game:

   When you press the button, the fighter aircraft will fire bullets

When you operating the PS2 Joystick, you can change the position of movement of the fighter aircraft.

Note:

1. In this experiment, my Arduino UNO board is connected to my computer port COM26. But it may differ in your case. So please adjust it according to your actual situation.

2. If the Processing does not run normally, you may need to install the related function libraries.


Procedures

Step 1: Build the circuit

  Serial.print(yval);//Dend yval value
  Serial.print(',');
  Serial.print(btnval);//Dend btnval value
  Serial.println(','); 
  delay(100); 
}

Step 3: Compile the program and upload to Arduino UNO board


Step 4: Run the Processing software (Processing_PS2Joystick_Button.pde)
