Description

Pusherduino is an Arduino based, simple and excited board game. Follow the comments in source code for more info.

Basic explanation of the game : There are 4 buttons and each button has a led. When the game start, one led is turned on. Gamer should push the button of the led in the given time interval. If gamer can push the correct button, s/he will make a score and delayTime will decrease. If gamer push the wrong button or cannot push the button in the given time interval, s/he will lose a life. If gamer makes a combo, s/he will gain a life.

Not : If you will build the game on your own Arduino, do not forget to put resistors for LEDs.

/*GAMEL LOGIC
There are 4 buttons and each button has a led. When the game start, one led is turned on.
Gamer should push the button of the led in the given time interval. If gamer can push the
correct button, s/he will make a score and delayTime will decrease. If gamer push the wrong
button or cannot push the button in the given time interval, s/he will lose a life. If gamer
makes a combo, s/he will gain a life.
