In this blog, i will show u how to make ping pong game in Arduino.
Requirements:
Arduino Uno, Arduino IDE, Potentiometer, LCD OLED (0.92 inch, SSD1306), Buzzer
connection (image soon):
code:
#include "ssd1306.h"
//function "handleDirection" not working properly, fix it
const unsigned char playerLineIMG [] PROGMEM = {
0xFF
};
const unsigned char ballIMG [] PROGMEM = {
0b00000011,
0b00000011
};
const int plrWidth = sizeof(playerLineIMG);
const int ballWidth = sizeof(ballIMG);
const int ballSpeed = 1;
const int toneDuration = 100;
const int toneFreq = 1046;
class Player {
public:
SPRITE playerTop = ssd1306_createSprite( 0, 0, plrWidth, playerLineIMG );
SPRITE playerBottom = ssd1306_createSprite( 0, 0, plrWidth, playerLineIMG );
void setPlrX(int x){
playerTop.x = x;
playerBottom.x = x;
}
void setPlrY(int y){
playerTop.y = y;
playerBottom.y = y + 8;
}
void drawPlr(){
playerTop.draw();
playerBottom.draw();
}
int getX(){
return playerTop.x;
}
int getY(){
return playerTop.y;
}
void erasePlrTrace(){
playerTop.eraseTrace();
playerBottom.eraseTrace();
}
};
