Introduction: Arduino Rocker Game

This instructable will show you how to make this simply fun game called the Arduino rocker.

Step 1: Materials

Here are the supplies needed to complete this project:
10 200 ohm resistors

9 LED lights

a push button

jumper wires

breadboard

Arduino Uno

Step 2: Connect the Materials

Every LED should be connected with a resistor from pin 2 to pin 10.
Follow this fritz, then connect the button to pin 13 of the Aduino (don't forget the pull down resistor). Connect the ground GND pin to the ground rail of the breadboard If you have troubles follow the pictures.

Step 3: Upload the Code

Start with the blink without delay example in order to understand the final project.
Once done, load the final project. Make sure that the proper board is selected! You have three lives, every time you click the button when the light is not on the middle LED, you lose a life. Once you run out of lives, the game restarts. When you click the button when the light is on the middle LED, the lights rock faster. Thank you and good luck!

Here is the code

int LEDpos = 1 ;
int leds[] = {1,2,3,4,5,6,7,8,9}; int ledStateA = LOW; int var=10; int status=0; int button=13; int lives =3;

// ledState used to set the LED long previousMillis = 0; // will store last time LED was updated

long interval = 500; // interval at which to blink (milliseconds)

void setup() { //All LEDs are set as output for(int a=2;a<11;a++){ pinMode(a, OUTPUT); } pinMode(button, INPUT); Serial.begin(9600); }

void loop() { if(lives==0) //Setting starting interval { interval=500; }

//Detect if button is pressed if(digitalRead(button)== LOW ) { Serial.println("pressed"); if(LEDpos==6) // Button was pressed at the middle LED !! { interval/=1.5; // Reduce interval ; LED blink faster //Blink Middle LED twice for user to notice he won! digitalWrite(6,HIGH); delay(200); digitalWrite(6,LOW); delay(200); digitalWrite(6,HIGH); delay(200); digitalWrite(6,LOW); Serial.println("LEVEL UP"); } else // Button was pressed but not at the middle LED :( { delay(200); digitalWrite(leds[1], HIGH); lives--; // user Lost a life } if(lives==0){ interval= 500; Serial.println("GAME OVER"); } } unsigned long currentMillis = millis();

if(currentMillis - previousMillis > interval) { if(status==0) { if (LEDpos> 9 ) status=1; else LEDpos++; } if(status==1) //Reached the start { if (LEDpos<3) status=0; else { LEDpos--; if(LEDpos == 2) status=0; } } // save the last time you blinked the LED previousMillis = currentMillis; //Turn off all LEDs for (int x = 2; x <= 10;x++) { digitalWrite(x, LOW); }

//Turn on the LED digitalWrite(LEDpos , HIGH); }

}

Fun. You could turn this into a full sized carnival game.
